I had a trial lesson in a knackered old Warrior but did my PPL at the flying school next door in very modern C172s. I don't think it matters either way, you'll get used to whatever you learn to fly in.
High wing is crap for visibility but It was nice to fly and kitted out with all the fancy stuff.
I fly a low wing with a stick now and I love the visibility but I could quite happily go back to a Cessna.
If I were you I'd go for the cheapest option and use the change to convert to something more exciting once you have your licence in hand.
