For every bug handcent seems to have, there is an update soon to follow- thats one thing that I /love/ about it Besides giving me the option to change the color of absolutely everything on it.
One damn thing I wish Handcent would update, is a warning near the notification checkbox telling people to uncheck their notification box in the stock messaging application like ChompSMS does so we don't get three people per day asking why they are getting double notifications.
As a matter of fact, I'm going to email them and suggest that.
Been using Handcent since day one. Never had a single problem. It's like Matth3w said in another thread- every phone is different, so everyone is going to have different app interactions.
See no reason to try Chomp.
