I have one, and the thing that hooked me was the "feel" of the action. I wasn't looking for a rifle that expensive, but after playing with it, I knew I would always want to get one. Recoil lug, I don't care. None of the custom actions is going to have a recoil lug that isn't rigid or "strong" enough. The Pic rail on top, the advantage/disadvantage of integral is obvious. It won't come off. If you have one, no worries that it will loosen. Also no ability to change it if you want one with a different angle.
Mauser claw extractor? They can be wobbly and not as smooth as a round bolt,
