1st off, I've never ridden any of those bikes aside from a parking lot test... but every review I have ever read + quite a few people talking too rave about the Firebird's climbing ability. What exactly didn't you like? If it was just uncomfortable that could easily just be that it didn't fit you. If it was something else like the geometry or the way the bike pedaled then that's something different.
But to me it seems like you really really liked the Firebird... so maybe try to get one set up right and give it a good honest shot!
