Jason, quality is relative. You can make anything top quality according to it' s design parameters. In the case of two things with equal manufacturing quality, you need to talk about the design itself.
The GKF design is simpler and much more durable. A better quality design.
GKF' s look like they look like they were designed by machinists. NAP rests look like they were designed by engineers. (Machinists are the guys who have to spend hours looking at a blueprint, scratching their arse, trying to figure out how they' re going to make that engineer' s idiot idea actually work.
