Goodyear MT/R Kelvar vs Cooper STT

I am going crazy trying to decide between these two tires. I need a tire to drive to the trails about three to five hours on the highway, but does well on New England trails. Based on tons of internet research, I have narrowed it down to GY MT/R and Copper STT.
My concern is performance on rocks and mud. Only by what I’ve read, the MT/Rs are great on rocks, but mud reviews are mixed. Some say they are either, great, okay, or terrible. Coppers get very good reviews in mud, good or okay on rocks, but there have been comments regarding side wall strength.

My fear is having a tire pack with mud and being “that guy” always stuck, or in the rocks blowing out the sidewalls.

Are either my concerns serious enough to rule out either tire ?

Both are at a similar price point, in my budget, and tread life is good for either.
Both are similar to actual height, but the STT are narrower.

Can only comment on STT's. Love them off road, but, with your 3-5 hr hwy commute to trails, I will add this......
Coopers are quite around town but get very loud around 50 mph. That's on 33/12.5/16's at 26 psi.

Are the Goodyears quietier hwy tires .... they look like they would be?
The STT's are a lot sexier looking. Small point..... and JMO.

Don't think you can go wrong with either.
