That telescoping stock is tits. That has my vote.

I've shot mine with both and am currently using the telescoping stock. I think they're both pretty good. The folding stock, when folded, is much shorter. I like the way the collapsable stock feels when shooting better. I did have to take the collapsable stock apart after my last range trip because it locked up. There is actually an adjustment screw on the bottom if it ever happens to you. You have to remove the first screw you see completely to get to the adjustment.
edit: I'm also still wondering where you got that three lug adaptor

I vote telescoping as well.
Both are sweet. Edging towards telescoping...
