The Mid Click vs BetterTouchTool

If you only want three-finger middle click on a Mac trackpad, The Mid Click is the simpler option. If you want extensive gesture customization and automation, BetterTouchTool is the more capable option. Both can produce a middle click from a three-finger gesture; they're built for different people.

Can you run both?

Yes, as long as only one of them is configured to handle the three-finger gesture. If both act, you'll get two middle clicks.

What they have in common

Both rely on the same macOS mechanism: an event tap that observes trackpad touches and sends a synthetic middle-button event, which is why both require Accessibility permission and why neither is sold on the Mac App Store. More on the permission.
