This used to be the case but not anymore. ASUS, MSI, Gigabyte, ASRock are all fine usually for hackintosh.
If you just google "ASUS X99 Hackintosh" for instance, you get a nice page of [SUCCESS] posts and guides/video to the latest El Cap patch. As for Linux it's really the same from these premium motherboard makers, there's no "better" choice than the one you think is the best mobo for you.
The real difference is on a model-by-model basis, regardless of the brand. There are failures and there are great products, that's the way it is. So always google the exact model you wish to buy (based on specs and formal testing) just to see if there aren't too many horror stories. Add your build's flavor of course ─ "Hackintosh", "Linux", "overclock", "NAS", etc.
It's also great when you can return a product with no questions asked and get a refund like with Amazon, and then just buy an alternative.
For motherboards (and I'd say video card and RAM), these are all considerations that preside over brand choice/fidelity, if your intent is to make a "good purchase" (function and cost), imho.
