I think people are better off reading here to find vendor reviews and user experiences with various vendors. The Vendor Connection sub forum is a great starting point to find vendors, then search to find user feedback, and join your target vendor's discord/telegram and read more user feedback, testing policies, 3rd party tests etc.
The problem with a spreadsheet cheatsheet is it is impossible to keep updated with the latest vendor developments and can be incredibly biased by the person updating the sheet. With every new pep batch there are potential changes and drama from vendor to vendor. Case in point GYC - three weeks ago a solid vendor, today, much riskier.
