It seems a new twitter app comes out every day, however, this one has stood the test of time. Seesmic strikes a nice balance between the ridiculously full featured and overly simplistic competitors. It's useful without being complicated, beautiful without being cartoony, and, most importantly, it has everything any average twitter user will ever need without sacrificing speed and usability. It seems like I've tried hundreds of twitter apps, and was once a religious Twidroid user, however, when I tried Seesmic for the first time, I knew my search was over. Seriously, try it out, you won't be disappointed.
