I dont like R33GTRs at all, looks wise.
Performance wise they the same car really barring having slightly better brakes, and weighing more, which makes them feel a bit less nimble and chuckable compared to a 32.

You paying for a newer car, and a different looking car (which i think looks like a boring blob comapred to 32 and 34 GTRs), not for a better drive.

Only GTRs i really like, and ever really liked, is R32s, tho if i could afford one id have a 34GTR as well as a more mild tuned comfy day to day car, but i cant, and if i could id rather spend it on more mods for the 32.

Been in a 33, but never driven. Driven a good few 32s.
