Owned an LMT MWS308, own an SR-25 EMC, shot a fair amount of the SIG SAPR and the Hk MR308. Never handled a POF.
It's hard to say no to the LMT, for the price.
All the guns above have very high reliability (I've even run my SR-25 EMC with MFS 145gr., so it's not as finicky or as ammo-sensitive as many people claim them to be).
