More times than not, anime popularity contests end up as crap, so if I went with that, I wouldn't bother with anything at all xP On other news, the Rozen dolls went to have tea with Nanoha apparently, all three lost last round xP Kinda sad how the two greatest powerhouses can't compete anymore but I suppose time does that.
They are remakes to an extent, but with vastly superior animation and barrier jacker/device designs as well as some other new elements, they make for a fun watch to any Nanoha fan. The first movie has new backstory elements, and the A's movie adds content that was previously only in the mangas. Nanoha and Fate do Calamity Blaster in the A's movie, which is a combination attack using some of their most powerful spells. There is a bunch of other new content too. I don't think you would regret watching them.
As for your other reply, fair enough. No point going any further with that.
And I answered with 3 character names, as in "I don't know really who's in the character tiers below these" xP I mean all character are usually compared to either Madokami or Nanoha and how close they are to that level, so I didn't really sit and make tier lists xP
