PA 28
They Are PA-28's you have them with 140-160-180 HP and then the Arrow 200HP and retractable.
They are all the same, I gather you are a low timer. It will be just a bit more acceleration and the prop in some and the gear in others.
The katana is a sleek plane so it would help you with the PA28 since is not as sleek.
Good for you that you are trying new things, good luck and read POH
