8BitDo SF30 Pro

Pros

• It works on most systems via Bluetooth: Windows, Android, macOS, Linux (Raspberry Pi,) Steam and even Nintendo Switch. It also works as wired USB controller.
• Works well with modern Video Games, best on Nintendo Switch.
• As responsive as wired controllers, even in wireless mode.

Cons

• Setting it up for the first time is kind of confusing, you have to follow the manual correctly.
• SNES style controllers don't have handles, some people might have trouble with playing for a long time.

Comments

It comes om two types: SF30 Pro (RGBY Buttons) and SN30 (Blue & violet buttons.) There's even the Pro+ and non-pro versions but those are different products. There's also a wireless connector that lets it work on older systems.
