Abnormal Reco is quick with C shot, and wtfstupidfast with A shot. Overall I like that shot type more, but it's pretty much unusable unless you're really really good, since you'll move too fast and fly right into a bullet.
As for Normal Palm, he doesn't really feel that much different compared to Abnormal. His damage output isn't as high, though.
Reco really isn't that weak, though, despite doing less damage than Palm. She compensates by having a much, much wider range, too.
