OP have you had a chance to look at each upper and or shoot them?
I run an LMT upper 10.5 as my patrol gun and love it
i'll just point out the obvious.. pistons cycle harder, recoil harder, are heavier, and less accurate.
those are irrefutable facts... if whatever benefits they have outweigh those things for you, then get the LWRC. if they don't, get the LMT. they apparently do, for a lot of people- even though those lot of people cant ever really seem to articulate what exactly they are. :p
Kick harder? Less accurate? I shoot an LWRC 10.5" 6.8, about 1200 rounds so far, and I find the recoil to be mild, about the same as the DI 6.8's I've owned. The impulse may be sharper but my perception is its about the same in felt recoil. I can also shoot MOA at 100 yards with this upper, under MOA with my LWRC 14.7", using SMK's. How much more accurate do you need?
LWRC M6A1

Here's a five round group I shot with it at 100 yards

Here's a three round group at 200 yards

This was with a non-magnified Aimpoint T1 and standard trigger using a bench to rest the rails and using my hand to stabilize the stock. Put a decent magnified optic on it, put a better shooter behind the gun, and I bet the groups would shrink even more.
I've no experience with LMT but I've heard good things, you will probably be fine with either.
I'd have a 11.5" barrel instead.
It is less harsh on a silencer and proven to be more reliable no matter what anyone else tells you.
I have gotten rid of all my working 10.5" guns.
The only 10.5" stuff I have left is Colt MK18 stuff for collectability reasons.
And if you are set on LMT vs. LWRC, LMT is superior.
