I'm speaking purely on G80-3000 equipped with Cherry Blue switches
I personally didn't like it. There is such a thing as "too tactile" when it comes to gaming. A good example that I would use to test how fast my fingers could run over a keyboard is by quickly tapping W A S D W A S D over and over, in very quick succession.
Out of a Filco brown cherry, Blue cherries, and a Happy Hacking Pro 2, I was able to do this the best on browns...probably due to it's light resistance and almost zero tactile feedback. Next up was cherry blues but a big gap between the two. The HHK coming up next to it. My muscle memory seems to "wait" until the key feels like it registers when dealing with tactile keys. While that's great for typing, because you fingers can just do the work and roll gracefully feeling every tactile bump, with gaming, it feels sloppy, kind of a "mind lag". It's hard to put, but I didn't prefer it. Also the noise was annoying (the only time I was annoyed by blue cherries).
edit: might want to use two paper clips and hook the bend around opposite corners of a key, and pull straight up simultaneously and take a look at the color. Or make a recording of it, not bottoming out. Where did you purchase it from?
