Finished Akane's route yesterday, so now I have read all 5 routes. Even though I like the "old" Key style, I don't think I've enjoyed any route in older Key games as much as Rewrite's routes. Romeo really brought some fresh air into Key. And more of Ryukishi07 is always a good thing.
Thoughts in reading order:
Ranking:
Routes: Lucia > Shizuru > Akane/Chihaya > Kotori
Girls: Kotori > Shizuru > Akane > Chihaya/Lucia
I also really enjoyed Yoshino's character. I liked that he got a bit of characterization in every route, so after the five routes he really feels like a round character. Sunohara and the Little Busters boys got their development too, but not really outside their routes. I think prefer the approach Romeo took with Yoshino. Hopefully he plays a role in Moon and Terra, because I enjoy both his antics and his serious side.
A technical question:
Is it possible to copy my savegame? So far I read on my home pc, but I want to continue on my laptop. It would be a pain to skip through all five routes and most likely miss many of the sidequest during the mappie scenes.
