The main elements to evaluate are compatibility with your module, tracking capabilities, noise, feel, durability, and cosmetic appeal of the pads. You also want to make sure the pads will mount on your existing drum hardware. Many drummers will use a combination, such as rubber pads for cymbals and acoustic headed pads for the drums. If I tighten up my acoustic drum heads they feel different than they did loose. My high hats feel different than my ride.
Electronic drums are electronic drums and they feel great just how they are.
I am an electronic drummer and an acoustic drummer. Not an acoustic drummer with electronic drums. And my piano feels nothing like my little kazoo. I hope you get the picture. I hear alot of talk about how well this or that drum pad or brain tracks.
