AES50, DANTE, AVB, Cirrus Logic, CobraNet, Digigram, BLU, RockNet. All different standards being used.
Yamaha, Shure and Digico using DANTE. Sony, Panasonic, Midas using AES 50, this covers most of the live broadcast industry. Harman group and Avid using AVB.
I've used all the standards above.
Avid S3L I find frustrating. I'm a Midas user most of the time XL8 or higher Pro series. Use Digico often, SD9, SD7.
Used the CL series from Yamaha (plus other digital consoles). I wouldn't use Yamaha in a high-end professional environment. It's like a Vespa compared to a TT bike. Plus they sound terrible!
