Appetizer is my App.net client of choice. It is still in its early stages, but it handles the basic App.net functionality1 well.

I also have tried Mention and moApp. Mention is just not my style, while I feel Appetizier handles things a little better than moApp. Also, the moApp developer was kind of offensive on App.net recently and that makes it hard for me to support him. ↩
