I don't know that there's really any difference between micromesh and regular sandpaper, but I got the micromesh pad kit from stew mac. And I like it because it's cheap and convenient - they give you a whole range of grits, so you can knock the stickyness off, but then polish it up to whatever level of gloss you want by going up however many grits. I mentioned in another thread yesterday that I had some scratches on the back of my EJ strat neck. I was able to remove the scratches and finish it all the way back to gloss again with the micromesh such that you would never know that the scratches were there. The neck looks brand new. But I could have also stopped one or two steps short and had it be a touch more satiny.
Here's a long thread about micromesh:
