850 or 1000

So im ready to get rid of my renegade 1000 and get an outlander just wondering how much of a difference there is between the 850 and 1000 as far as power goes I know an 11 hp difference but I can get a leftover 850 for 8600 otd but cant find any 1000 left overs. I just don’t want to be disappointed in the power of the 850 coming off a 1000
