True.
But something like the MG AGE line of kits are very simple. I would consider them to be like HGs in respect to complexity, but they come out looking nice, and they have good designs and low price.

Hmm, I've never really ran into any kits that gave me any trouble, but I started out building 4WD cars, then BB senshi, then HGs, then MGs.

As for me, one thing I always avoid is impulse-buying just because some kits are new & hot. Just like you, I also made a list of must-buy kit that I stick with. Unless there's a really really good offer/deal of other kits, I always prioritize the kits in my must-buy list. So, if Exia Ignition has been in your top must-buy list and you like it that much, I'd say go with it. You can get Sazabi Ka anytime once you "re-fuel" your wallet.

PS: Actually, buying MG 00 Raiser is not pointless as the MG has better proportion than the PG especially when it's in 00 Raiser mode.

That is a good point...perhaps I can wait on the Sazabi Ka.

The thing with Raiser, is that I generally avoid getting 2 of the same kit (I have MG Gundam 2.0 so I won't get 3.0). I like to display different ones and since I plan to get PG Raiser I probably won't get MG Raiser, MG 00 Gundam or MG 00 Gundam seven swords.

As Obelisk said, the MG 00 has better proportions overall, and from reviews I saw seems the better iverall kit quality-wise. I'm very pleased with my 00 Raiser. If you want to get a PG, I would go with a different one. Oh, and the PG 00 doesn't come with that display base anymore :/

What would you recommend if I drop the PG raiser and opt for a MG raiser? I have GP01 already, and am not a fan of Strike. I heard MG Zeta 2.0 has better mechanism than the PG one as well.

PGs are just too cumbersome, expensive, and take up too much space. Sure they're in 1/60 scale and have the best tech for its time, but with MGs the way they are and have been, I would go with MGs only and maybe get some RGs if you're interested in it.

Me... I go 90% MG and 10% RG.

Get a MK-II Ver 2.0 if you dont have one already. A superb kit, just avoid the special HD coating versions.
Or if you want some grunt types a Zaku Ver 2.0, Geara Doga, Jesta or Zgok MG kit would also be a great addition.

IMO with PGs, get what you simply think is best looking and what you most want.
Way I see it is PGs are there simply for show, so you just get what you really want the most, as you won't(or rather shouldn't) be playing around with it alot anyway and display the bad boy in all it's glory as a center piece.
Shouldn't really compare PGs to the other scales.

If you really want the 00 Raiser then I say get it, doesn't matter if the MG is a "better" model, that PG will just look so much more than it's little brother:)

It's only between HG and MGs you should really consider whats better IMO.

If you're going to opt out of the PG 00 Raiser, and instead go with the MG 00 Raiser, then that's a good choice. The PG is expensive, although it has the gimmick of those moving GN Driver things that also have LEDs.

Personally, I can't recommend the MG 00 line of kits enough. They're all amazing, and with MG Exia Repair 2 recently announced as an online exclusive, then that means we have hope for the Exia Repair 3 at the least, and maybe even the 0 Gundam (ACD Type), 0 Gundam (Roll Out Type), Exia (Roll Out Type), Astraea, Astraea Type F, etc.

Aside from that, I would suggest the MG AGE line or the MG Wing EW line.

Those 3 lines of MGs are quite amazing and modern.

MG Seed is just something that I just started and so far I have 4x of the MG Aile Strike RM (to display as Strike, Aile Strike, Launcher Strike, and Sword Strike) since I also got the online exclusive add on set, and I also have the Aegis and the Strike Rouge Ootori.

Instead of a PG, I would get 1 expensive MG or 2 or 3 regularly priced MG.

HG vs. MG is no competition. If there is a MG version of the same kit available as HG, then I always suggest MG. Really. All HGs eventually turn up as MG eventually be it through regular release or online exclusive.

Hmm, which one is simpler to construct? MG Guncannon or MG Ball?

No, this is not a joke question. I'm planning that IF I eventually skilled enough with HG, I'll get MG that is not a Gundam.

MG Ball is easier.

From 00 I like Exia, then Raiser, everything else is meh to me.

Not a huge fan of Strike either, but I do have a Freedom.

The spinning GN drive is one of the key things I want from PG raiser, but we'll see.

Gundam Mk. II might not be a bad choice for PG kits...

With Gundam 00, I think most people generally like the Exia. Which might be why we're seeing the Metal Build Exia figures, and now the MG Exia Repair 2 (online exclusive). Maybe we'll see the MG Exia Repair 3 as another online exclusive later.

I like the Strike design. It's like a more streamlined & modernized version of the RX-78-2. Freedom and Strike Freedom are a super fan favorite suit.

The GN Drive gimmick on the PG 00 Raiser isn't worth it. I'd rather just get the MG 00 Raiser and get a whole bunch of the LED units. Also, I'd add on the MG 00 Gundam 7 Sword G.

For the Gundam MK II, just get the MG ver 2.0.

Again, it's all up to you but PGs aren't worth it for me:

a. very big
b. takes up a lot of space
c. takes a lot of time to build
d. premium quality expensive

I don't have any PG's yet so I can't speak out of experience, but I would say either Strike Freedom or the Red Frame. Preferably the Red Frame

Honestly, if you want the 00 Raiser, just look up some pictures online, if you like what you see, buy it. Whether or not MG 00 Raiser has better proportions is subjective anyways.

True. But the value I find in the MG line of kits is far more rewarding than SD, HG, PG, and RG.

Give me some of your lovely dexterity plz

Get Exia R2 when it comes out xD, IMO its the coolest Exia and since it's exclusive it will be a little something special for your shelf (might be a little pricier/on same level of the Ignition mode, definitely less than Sazabi ver Ka. though)

Check Dalong xD, if you go to the information section you can look at scans of the manual and make judgements for yourself on build complexity

What you see in a-c is exactly why I want a PG. Having one big badass, detailed MS towering over the rest of the collection is awesome.
