Stock bearings are pretty beefy. You'll be hard pressed to find anything that'll work much better without paying a ton for something specialized from what I've seen. My guess as to why it's common for all of them would be that the costs to design and implement different designs for different trims likely wouldn't be offset by the slight decrease in piece cost.

You can get OE AC Delco front hubs from Rockauto for $77ea, and I see no good reason to do anything else.

They're all X-tracker hubs. I've spoken to SKF directly in the past to confirm. X-tracker is primarily a bearing orientation design, and luckily GM went with this design for all the Camaro hubs (and likely many others) which keeps costs low. I agree with you that it's probably best to stick OE in this case. The SKF bearing is what went through all the development/validation at GM which includes some pretty serious track use. Others like Moog/Centric probably didn't, and their costs are likely higher simply because they aren't equipped to produce those parts at the volumes SKF does with no performance/quality benefit.
