Are there major differences between GPU manufacturers? What’s the difference? Is it mostly just cooling, overclocking, and looks?

I do not have the full working knowledge but NVIDIA sells the GPU die to companies like Gigabyte or MSI, within these–like you said– cooling, overclocking, and looks are different. What also can be different are the internal electronics.
Linked below is a 5070 ti, which has different BIOS based off the various models, each has similar or different power maximums based off the different architecture the companies release.
However, you can flash any BIOS you want to a 5070 ti in that list, and I think you could flash a 5090 bios onto a 5070 ti, but I could be wrong there. I hope this helps.

you pretty much got it. Other things that board partners also have control over is the quality of the components that they use(like the mosfetts, capacitors and chokes for example). How they set up the VRM circuits and internal safety circuitry. Like I believe the 5090 Astral card is the only one using separate VRM’s for every wire on the 12V high power. One of the reason why it cost so much. Another thing is some of the 9070XT’s are using a 12v high power while most others are just using dual eight pins. The chip manufacturers lay down certain guidelines that the board partners have to follow everything else is up to them. This is one reason that EVGA gave up on GPUs. They wanted to build their way, and Nvidia had too many restrictions.

Oh wow, so sad to hear about EVGA, I liked them
