pro all the way in my opinion
I have a buddy that is 6'-5" and 375lbs, he has been riding pros last 2 yrs and can keep up with just about anyone, he is adding a silber turbo at the moment to even the playing field a little more, the pro gets up on the snow better than any sled out there, even most doo riders will admit this if they're honest with themselves, I used to be one. Everyone has a preferance, you honestly can't go wrong these days, ride all three in as many snow conditions as you can and get what you like best. I am 6' and 275 with gear and I am on a pro last 2 yrs also, I leave alot of guys at the trail, they can't follow in the deep and trees. If your a point and shoot guy I'd look towards more HP, from a turbo, or a cat or doo, but for all around mountain riding I think the pro wins in my book. As far as the above post saying Pro's are made cheap, I don't think carbon frame structures and industry leading innovations are cheap, they did have a slip with a sub-contractor making the driveshaft, but when you lead the pack your gonna have a few fixes. As far as quickdrive belts stripping, if the break-in procedures were followed you shouldn't have a problem, There is not one that has failed among my riding group. Also in the group are a few boosted pros, some now with over 500 miles, and no issues, you be the judge? Good luck on your choice.
