Hoi,
I think it is more important to focus on a good school than on what aeroplane you are going to fly.
It may depend a little bit on whether there are any monetary or weight constraints to take into account.
If you are heavy you would be better to do it in a four seater, if money is tight in a two seater and if you can not make up your mind have an hour in each and see what you like best yourself.
High or low wing is very much a matter of taste.
