Personally, I think you need to do some serious research. Your opinions of the 3 or 4 schools you are interested seem to be based on flimsy conjecture and the opinions of a few pilots.
Do you think going to Oxford will give you a large advantage whn applying-is the advantage that you will get worth the extra money you will pay over and above Cabair or anywhere else? I suspect the advantage you will get won't be worth the extra money-in my honest opinion.
I'm not meaning to be nasty-far from it. I'm meaning to make you do proper homework, and maybe save a lot of your (or your family's) money into the bargain.
