I did my PPL in a C152, and am in the process of getting signed off on the PA28. As Evo7 said, they're fairly tame in comparison to small a/c, such as the truamahawk and C152. They are a lot more spacious though.
I would think they'd be fine for training, but if you can get some time in other a/c once you've got some hours in then do so. It's all good experience!
