The rifle works with the JP unit and compared to other other spring and buffer combos, it delivers what you find to be a smoother recoil impulse and faster sight picture acquisition for follow up shots.
Since the rifle as is runs to your expectations, I think what you need to do is define and focus on what you mean by durability, reliability, and accuracy.
To me, the only questions are what are the failure points of the JP unit? What happens if it becomes 'uncaptured' while in the rifle? Would you even know it while firing? Are you counting on this rifle as your primary HD weapon?
If I were pondering this decision, I'd rock on with the JP. But I have an SBR for HD that I only shoot to verify function and zero, then clean, lube and put away till next time. All my other rifles are toys.
