It's about what you like and what you're gonna do with it. If its gonna be mainly a driver and only off road on occasion then the 17s would be fine. For rock crawling, not so much. I like the look of lots of sidewall on my jeep. It has 15" wheels and 33's. But my Titan has 18" rims and 32's and they look way better on it than my jeep wheels would.
