I did my PPL on a 150 and a 172 and now fly mainly low wing aircraft. However, I think the Cessna 2/4 seaters are a bit like the VW Beetle...if you learnt on one it has a special place etc etc.
If cost is an issue, simply go with the cheapest, if it isn't...can I have a loan?
Wherever you end up flying, you'll need to do a check ride at the very least before you can hire and will want to do a few hours under the guidance of an instructor to get up to speed with UK airspace and these could easily be familiarisation time on a new type.
My opinion is that speding the extra to take to empty seats flying for 45hrs PPL training is probably not necessary.
