I'm using one too and I love it. The scroll wheel isn't quiet when scrolling really fast, but it's sooo nice to use. Downsides are the slow polling time but even in multiplayer shooters I do fine, the cost, and the software is kinda bad, not the worst but not great. However, the gestures are great, I use them all the time. Thumb button gestures I use left/right for volume, one of the side buttons I use left/right for snipping tool/text extraction. It is on the bigger side but being semi-"ergonomic" it might fit better (or worse), not sure, I have not-small hands.

I couldn't give less of a fuck about leaderboards, but I enjoy seasons in D3, but not D4. In D3 you get to max level and get a set of pretty good gear in a few hours. I'm a casual player, I don't play the entirety of the season because I kinda hit my limit and stop getting new shiny things and don't feel like pushing it so I stop playing. Then a new season comes out, I'm like "I haven't played Diablo in a bit, that sounds fun" and I do the same thing, smash monsters and get shiny things.
In D4 the new season landed and I just couldn't be bothered to level again and it really killed the game for me, I'm kinda maxed out on non-seasonal, it gets to the point where you're doing the same thing over and over for hours, or you push harder content where it takes forever to kill something and everything kills you in one hit. I just want to smash shit and get loot, I don't want to level again if it takes more than a couple hours.
Basically seasons can be fun (also they test new content, that keeps things fresh) as long as you can jump right back into the game. Without it you have a ton of legendary items for every class so you just never really need new gear, you just grind for that single piece you need for a 2% upgrade.
Tldr I don't want to grind, I just want to smash baddies, and I'm basically a bird collecting shiny shit. D3 enables that, D4 doesn't. It's all about implementation.

It is quiet in normal use but when I'm scrolling quickly and stop suddenly it does clunk a bit, but that's really the only noise it makes.
