I went with AKG Motorsports's offering. I liked how you could select which durometer you wanted and went with the 80A variety as the car is still street driven. I got both engine mounts and transmission mounts installed at the same time so I cannot comment on them individually.
That said, my NVH experience is as follows. The mounts will increase the chance that OTHER objects in and around the cabin will exhibit NVH. In other words, the effect of the mounts themselves is simply that the car feels more raw. Engine idling is more pronounced and the transmission feels more mechanical in its operation. After tracking down some rouge plastic plugs and clips throughout the cabin, NVH is minimal and not something I notice anymore.
