Firstly, what's with all the flaming? The guy wants some input and preferably from people who've owned/driven either.
How are we meant to demonstrate to the general public that Skyline owners aren't hoons and terrors to society if we can't provide basic advice.
Appreciate that these threads do pop up on a semi-regular basis, but that's why the Internet is there.
OP, in relation to your post, if you're truly split, then drive a few and see which one speaks to you. You might drive a few 34s and think that they're the dogs bollocks, but then drive one particular 33 that you really love. Then your decision right there.
