|Which is better, Ford, or Chevrolet? Depends on who you ask.
The key to it is you. Albert Einstein could teach you physics, but if you don't do the homework and put your effort in, then his talents would be wasted.
Go to both places and spend a few bucks buying coffee for your potential instructor, and find out who you like. Remember, you're going to be spending a fair amount of time jostling shoulders with them, so if you don't like the way they look/speak/comb their hair/slurp their coffee, then you might want to find a different instructor. Then, treat it like a part-time job: show up early, with your homework done, and ready to go. Review afterwards, and fly regularly. That's a big one right there - try and have the cash for at least your PPL up front and ready to go, then you can go twice/three times a week, which will stop you from doing the 'two steps forward, one back' progression - saving you money.
There's tons of other suggestions on here - just trawl through the forum, or use the search, and you'll find them.
