HELP: What Would YOU Buy?!

I’m a first time ATV buyer and have decided that I’ll be buying a used GRIZZ. I have narrowed it down to two bikes and would love to hear your feedback / input on what one to buy:

1) 2012 700 EPS w/ 1400 miles and winch. Good condition, second owner. $5,800.

2) 2014 550 EPS w/ 500 miles. Great condition, original owner. $6,400.

I’ll be mainly using the gross from trail riding so performance and top end speed is key as well as some light utility use. I originally thought the 2012 was a no brainer given the 700 engine but after doing more research, it looks like 2014 was a huge upgrade year for the Grizz. What one would you recommend? Do these seem competitively priced? All input and opinions are welcome, thanks!
