At the end of the day, all personal preference anyways......so many good products out there. .308 caliber is definitely more accurate on the LMT MWS, but it's well documented the 6.5 creedmoor is not (LMT will only guaranty 1.5 MOA, which is terrible, and completely defeats the point of getting a 6.5 CM IMO). Still think you can build a more accurate and lighter rifle than LMT......the build he has listed out will likely shot as accurate as the LMT, and probably save him a few $100s.
