2 extra buttons on top and maybe 6 on the side at most I’d say before it starts getting hard to click, so like a 12 button mouse at most. but I’ve found 8 button mouse to be the most comfortable for me and it’s what I’d recommend for MMO’s and age, but that being said if you can learn to use an 18 button mouse it’s a huge help, makes it so quick to react, but if you’ve only used a 5 button standard mouse up to now might be too steep a jump into 18 buttons right away. They tend to be pricier per button too.
I’m on the basalisk v3 by razer rn
Practice and shape are most important. GPX clones are a safe place to start, Mchose A7 V2, ATK A9, Incott G23 V2. If you prefer a bit larger but still symmetrical, there are Viper clones, but I've only used one so far, namely the Eweadn S9. If you want larger ergo mice, my current main and favourite is the DeathAdder V3 Pro if you can find it for that much, otherwise if the wire doesn't bother you the regular V3 is the same but cheaper. If you need more buttons and don't mind the weight, Basilisk V3, I tried the G502X but the Basilisk felt better for me.
Since they already mentioned the Basilisk V3, I'd chime in and add that you should check the used market for one. I got one off Vinted for half the retail price where I live and it's only "issue" was that it had no original packaging, the mouse was practically brand new.
FWIW, I used a G500 for close to a decade without any issues. When that died, I swapped to the G502. Within 2 years, that one started doubleclicking. Got a replacement. That one started doubleclicking within that same year.
My friend had multiple G305s that also developed doubleclicking issues.
That's all to say -- there was/is absolutely a problem with the mechanical switches used in those mice. No idea if they've fixed it now, but I swore off Logitech mice as a result. I used a Razer Basilisk V3 for a little over 3 years with 0 issues, and only recently swapped over to the wireless version since it was on sale and wanted to swap away from my wired one.
My G502 just started to double click after 7 years, so I went to buy a new one. I exchanged it twice and all three had quality issues. (Slippy pads falling off, sharp plastic edges, and a bad scroll wheel).
I'm picking up a razer basilisk v3 today, the demo unit at BB felt pretty good. Not thrilled, but if Logitech can't make a product as good as it was then I'll try someone else.
