In my opinion it’s hard to beat the Sweet Rocker Full Face for comfort and protection. They are a bit pricey, but afterall it is your head. You can catch them on sale periodically, especially if you’re are open on color. Backcountry has a blue one on sale right now for $215.00. I wear a size 7 hat and the M/L fits fine.
I wore a Moment for a number of years with good results. Took a big hit while upside down on the Upper Nanty which resulted in a large bump on my head under the helmet. Obviously it did it’s job because I’m talking about it. I went to the Sweet after that.
Good luck with your decision.
