Crazy as it sounds I never liked the Supra or Acrolite, despite all the hit recordings it's been on. Actually never cared for any Ludwig snares I've tried, including Jazzfest, BB, Pioneer and Super Sensitive. Never tried a COB Supra though. I totally agree with the Gretsch COB 4160 snare mentioned by others. Totally underrated and unfairly shamed with that "all Gretsch snares are boxy" stuff that's been floating around for 50+ years. It cuts through the music but isn't obnoxious. I actually prefer them with the Lightning I or II strainer - the Micro (both new and old) gave me some issues. Also, don't sleep on the Premier Royal Ace. I love, love, love those snares and can sometimes be found for decent prices, but when it's time to replace the parallel strainer or wires, you're screwed. Slingerland Hollywood Ace would be my third choice. Actually prefer it to the Radio King.
