I think weight is the main thing to take in to consideration. This answer is coming 100% from me and I know lots of people feel the opposite.
The thing just weighs to much, for me personally the power to weight ratio just isnt worth it, I ride all conditions I can, climbing shoots, boondocking, jumping, open pow fields ect. The thing is just too heavy. You wont get the ease and playfulness you get from a 2 smoke, let alone a turbo.
Now if you ride strickly shoots and climb a ton it might be for you but otherwise I would think twice. Im not one of those people that say 4 strokes arent for the trees, Ive seen what can be done by them in the trees but it takes an extremely good rider and one that is in good shape, they are a lot of sled for someone to handle specially in the tight trees.
Now the only real answer to which is should get would be to go ride one for yourself and then decide later.
