old lenses - Which vintage lens mount is most suitable for EOS cameras?

I've been doing some research on vintage lenses to buy with the focal length of 24mm or 28mm as an alternative to the more expensive canon 24mm F2.8.

Best options I found were the FD version of the same lenses, Tokina 28mm F2.8, and Yashica 28mm F2.8. I found people selling the adapters for these lenses to an EOS camera on Amazon, but many articles on the internet do not recommend buying certain adapters since the quality will drop.

Are there certain brands or lens mounts that I should stick with that would not cause focusing problems, like not being able to focus at infinity, and that would not cause quality to drop?
