I'll be the odd ball and say excavator, especially for 12"+ roots. I have ran both and an excavator for this type of work will be faster, from my impression of what you're asking. A dozer will work but roots can be a job for a it. An excavator {something like a 307 cat} with a balde will run circles around a dozer. It is also easier to take out the whole tree{rootball and all} while it is still standing, IF YOU KNOW WHAT YOU'RE DOING !!!! Now if you're just worried about leveling simple ground then go with a dozer.
I can take out 12 inch + with my D3b Cat dozer, 1 pass knock over, back up and lower blade and take tree with rootball to the pile. When I am traveling backward on the dozer, I am dragging my blade and leveling. No time wasted that way. Not much left to do when finished with the dozer. Ken Sweet
