Tree Stand Pros;
Better sight lines
Better Scent control
Easier to pull bow back without being "busted"
Fun with birds and squirrels
I too am 6' 1" at 210lbs. and haven't had a problem yet.

Cons;
If you did not pick a good location it's a hassle to move (to a degree)
Cost (this too is subject to one's pocket book)
Not as safe as being on ground (archery only, for the most part)
No fun with birds and squirrels

Ground hunting is a bit more tougher IMO.
