What ATV should I get?

Hello, I am 6'2" 300 pounds and I have just recently blew up my yamaha 350 warrior. I am asking opinions about what quad I should get. I really want a 450 but I do a lot of trail riding and i was told a 450 would blow up easy since I wont be going that fast in the woods. I was told to get a 400 but all my friends have 400's that say that though and not to mention im a big guy. I was plaining on getting a yfz 450 but im not sure what manufacturer would be more reliable and what one would be the fastest. Please help I really need advice! Thanks.
