if its to be a daily driven car, and your first turbo car, i'd def go the gtt. you will be able to get an excellent condition gtt for the price you're looking at, but only an average GTR.
also, you will undoubtedly spend money on both throughout your ownership, but i'd say the GTR is more likely to sting you pretty hard.
another thing to think of is insurance, get quotes and add that in your budget.
good luck
