Alternative to No-Intro? Roms...

Hi, I have an Xbox Series S. Retroarch and Developer mode. I want to add Roms. SNES etc... Are there any Alternatives to No-Intro? I want high "Purity." Has anyone used Cylum's? From archive.org? I only need US Games. No other. I heard SOTEC is not good. So can anyone find an alternative to No-intro? Please reply. Thanks 

"No-Intro catalogs the best available version of ROMs"

Do you mean TOSEC? It indeed includes many versions of the same rom, including hacked and cracked.

no intro is just an organization, there's no real world difference nowadays between the roms, some people just like to label them their own.

Thanks for the Fast replies. Sounds good. I'll report back...

Can I get a Link? Full Romsets? Not archive.org?
