I also use a bamboo, and I like photoshop okay. Any program that has pen sensitivity is gonna be preferable. For reference, if your lines are all uniform in width, then pen sensitivity probably isn't on or isn't a feature. (With photoshop it sometimes doesn't register, so I'll close and reopen the program until it does. The easiest way to tell is make the brush huge and do a single stroke to see if it comes out blocky or like a paintbrush stroke. Paintbrush good, blocky bad!)
