Take a look at the Logitech G600. It has 12 side buttons and a shift mode that lets you map 12 more actions to those buttons. It has onboard memory rather than needing a companion app. Linux compatibility is great as it can be programmed with Piper. Only downside is it’s a bit large if you have smaller hands.

I would disagree if gestures being faster. Mostly because animations can’t be disabled with gestures.

If I hit the home button I am instantly on my home screen rather than waiting on the zoom and shrink animation. Same issue with recent apps.
