You should see the look on people's faces when they realize my SteelSeries Sensei has a small LCD on the bottom - https://steelseries.com/gaming-mice/sensei

Bought it because you can do simple macros for buttons which are stored on-device. Also allows for mode switching with rotating profiles that are differentiated by LED color.

If you're on a budget and don't care about on-device macros or looks then there are branded variants, like the Guild Wars 2 one when I initially tried it out and now there's a CoD one.

The downside is that the branding paint job wears out with use. Especially problematic on the white GW2 one I had (yellowing under fingers). Don't try to clean it with IPA (rubbing) alcohol though, it dissolves the matte sides and the paint job (learned from experience). https://www.amazon.com/SteelSeries-Call-Black-Gaming-Mouse/d...

I switched from Logitech to Roccata few years ago. The Type mouse has worked pretty well for me, with 14 programmable buttons

I think the keyword they use is ambidextrous. E.g. Zowie makes some decent ones that look fairly normal.

Gaming mouse, razer naga and naga hex have plenty of extra buttons. 15 and 6 respectively.
