Need help deciding... 2018 XC300?

[Wypipo]

I?ve narrowed down my choices between an 18 XC300 or a 19 beta RR 300.

I live in northern Idaho. 90% of my riding is tight mountain single track. A couple of races per year which are mostly single and 2 track but at a much faster pace. I love blasting up steep, rocky, nasty hills which I have a lot of around here. Looking for some honest feedback on the XC300 for my type of riding.
The suspension has me very interested in this bike. I?m 5?11 200 lbs without gear. Will the XC suspension be plush in the slow rocky stuff and soak up everything at speeds (root wads, roots, etc)? I understand all of the issues with the battery and starter got sorted out and is no longer an issue? Does anybody else ride this bike in similar terrain as me? Any complaints? Also anybody who has ridden the GG and a beta could give me a comparison? I am familiar with beta but not GG. And at 1,000$ cheaper for the 18 it is looking pretty nice. Also I have her choice between an EC and XC and I?ve heard different things....one dealer told me they?re exactly the same besides the lights and pipe. Anther said the flywheel was different and slightly different power, that the XC has a little more off throttle power. Can anyone comment?
