Also consider these

They have gyro and rumble which Hori doesn't have. They are also battery powered so they operate not connected to the switch. The Hori ONLY work on switch.

Also these sit flush with the top and bottom of your switch, unless the Hori which protrudes very far up over the top of the switch.

These also have rear buttons, turbos, LED light rings (color and modes can be changed or set to off)

This is current latest updated model of the binbok's linked above.

Just check the reviews and youtube videos of people who own them. While they are not the perfect (and frankly I've found nothing out there that is) they are the closest to the Joycon experience I want. Proper grip design, all of the benefits of the switch joycons (minus the amibo) and some added extras that joycon and Hori lack.

PS: I have the Hori Split Pad pro. The only positive I can give for it is that it has really good buttons. That's it. If Binbok had Hori's buttons it would be hands down the best in slot joycon for switch. As it stands now, it's close to the best in slot, but not quite perfect. If I had to rate binbok, I'd say 8.5/10. My only problem are the buttons. They are ok, but not stellar (neither is Nintendo's default joycons though)
