Can anyone provide feedback on the action Army Hop up performance over a TDC mod with a dangerwerx Hop up arm?

I had an AA chamber before and can't recall how well it shot. I'm doing a new build and wonder if it would be better to stick with the tried and true TDC mod and an R Hop.

Thanks for the feedback.

Unfortunately consistent fps does not correct bb spin. The TDC mod and the action Army chamber are designed to help, I would like to know which is better
