I got the 2x4. I already have a Grizzly and find that I dont really ever have to use the 4x4 on it. I got this bike for my girlfriend to ride and the price is very reasonable. Handles much better than my griz too in my opinion. The Griz has all the the things this one doesnt (fuel gage, clock, speedo, etc) so I really wasnt concerned with this one not having them. If it was going to be my only bike I would probably get the 4x4 just to have it. Hope that helps.
I can say what I mostly do and that is ride in croom or ONF etc. I just want to experience something different than the grizz so we can trade off back and fourth. I want it to be fast but it doesnt have to be the fastest. I dont have much desire to race or anything else as of now, but you never know.
