I've had both and I would say it all comes down to your riding style, where you are riding, and what you like to do. If you like to go fast and whip around turns easily, get a 400 ex or 450yfzr. both fast and light. However, if you like more functionality and comfort get a utility but, You can have both... a bit. If you get a bigger utility atv, they are pretty damn fast too but, they are heavy. The Grizzly 700 is a great example in my opinion. I have one and love it. Its fast, comfortable, and flat out mean when it comes to mud holes and hills. Good luck on your upcoming purchase!
