Most people would say LWRC is better.

I've never had a single malfuction of any kind with POF.

I had TONS of malfunctions with my LWRC IC-E during the break in period. NOTE: I was shooting Wolf ammo in a piston rifle with an H2 buffer. I probably would have eliminated most of the problems had I used an carbine or H buffer.

My LWRC M6-SL has had zero malfunctions.

My LWRC IC-EB has had zero malfunctions.

Statistically the POF is superior.

I prefer the POF's gas system from a maintenance standpoint. You don't have to remove the HG to maintain it.
