I currently run 2 Decimator II's (one in front, one in the loop) on the board of my main rig. Overall I've been happy with it over the few years or so I've had the setup. I also link them, though I don't notice much of a difference in doing so. Prior to ISP, like most people, I used an NS-2. The reason I made the change (again like most people) was the promise of less tone suck and better noise reduction performance. I was playing around with my old NS-2 the other day and it really made me think, aside from some high end loss, this is still a really good pedal. I actually do prefer the separation of the threshold and decay controls and really wish isp had something like that. With the decimator, I find that to get close to the same tight gate effect as the NS-2 with the decay at 0, I have to set the threshold somewhere around 1-2 o'clock. Upon setting the threshold that high though, I start to notice it affecting the tone, sustain, etc. and then I'll try to make adjustments elsewhere in the chain to balance things out. TL;DR: Has anyone tried something like a modified NS-2 or a decimator + something else and had good luck clamping down on noise, achieving staccato precision, and maintaining sustain? This interesting fellow has a cool vid on an NS-2 mod. His tone and playing aren't too pretty but I like what's going on with the gate performance.
