Anyone have input here?

I'm trying to decide which I like, yammie noob had a cool vid comparing the two with the xsr seemingly on top, but spec-wise, the z900 should be wild. I'm aware there are tune and exhaust kits to wake the undertuned z900 up.

I like spirited riding, but mostly on straights as I roar off to a campsite in the mountains. What do you folks think?
