This is my first post as a new member of simviation

After being a flight simmer of very limited skill since fs98, I have decided to delve into the real world of aviation and have 2 flight schools near me in the Vancouver BC area. Both have good credentials and price is relatively the same. My question is, one school uses a Piper Cherokee PA-28-140 and the other a Cessna 172. Is one aircraft better to learn on than the other? I know a couple of people that have advised me using the Cessna since it can be found at just about any airpark thus being more accessible if I'm on vacation and would like to rent one. I would like to have the opinion of all you real-life pilots out there. Please state your pro's and cons of each aircraft so I can make a more educated decision.
Thanks all.
Happy flying ;)
