I keep going between the default app and handcent. The only thing I really use handcent for is to go beyond 160 characters in my messages by splitting them.
I use the default one. I noticed Handcent likes to lock my phone up sometimes, forcing me to pull my battery.
i used to use handsent and i really like it for the custom things you can do but i uninstalled it and right away my mytouch ran alot smoother with no keybord lag. i just use the default now with the sms popup app. everything runs smooth i also used to have issues downloading picture texts with handcent. none with the default however.
been using handcent the second i activated the phone and i love it. it sometimes force closes but usually when the popup feature comes on.
definitely handcent. i used chomp, but it does't have the wonderful quick options in the sms popup like delete, add to contacts etc.
