I'm 5.7 tall and weight 140 lbs and I'm having a hard time getting a proper cheek weld on my MOE stock so I'm thinking about the bravo or enhanced for a bigger cheek rest which one do you guys prefer?

Do you mean the b5 enhanced and sop mod?
Both have same cheek weld but the enhanced has storage space.
Either way both have more cheek weld than the moe

Yes that's what I meant just edited the title

I have the B5 Bravo, MOE, CTR, STR and Vltor IMOD (I don't currently have a B5 Enhanced SOPMOD but my STR and IMOD are similar with big cheek rest), it depends what type of carbine and optics I'm using.

For my home defense and SHTF (lightweight and M4 type) carbine with a red dot optic I prefer my B5 Bravo, it have a little more cheek rest than my MOE and CTR stocks, but I don't like bigger cheek rest because I aim and carry frequently when I'm using this type of carbine.

When I use my other precision carbine with a heavier profile barrel and magnified optics I prefer the ones with the bigger cheek rest like my STR and IMOD because it is a steadier cheek weld, also the stock are heavier and balances the rifle better.

I've got the STR, UBR, Bravo, B5 sopmod and enhanced. The enhanced is by far my favorite and is on all my go to rifles.

Check out LaRue's R.A.T. Stock.  Gives me a good cheek weld. Locks up tight too.
