I gotta say, after the 2.1 update, I have fallen in love with my moment. Everything is so smooth and it takes anything I can dish at it so I say that its a good choice (expecially with launcherpro which gives you a nexus one like launcher which looks sooo awesome) but the evo is a complete monster. If the qwerty isn't a 100% dead-on strict requirement, by all means, get the evo you won't regret it.

I absolutely love my moment (imho its sprint best all around device up to date) but ill trade it for the evo the first chance I get
