Could it be the Micro Swiss you’re thinking of? AFAIK it is ok, though a bit over priced. Personally I would stay away from the cheap clones you find on Amazon/Aliexpress/Wish as the quality can be a bit of a gamble. Other CR-10 compatible hotends that I’ve heard good things about include Phaetus Dragonfly BMS, Mellow NF Zone, Slice Copperhead. If you just want an all metal CR-10 style hotend I would get one either from Trianglelab or Mellow, who are known to have relatively good manufacturing quality. They’ve gone up quite a lot in price so they’re almost as expensive as a Micro Swiss. Best value option is probably to just buy a high quality all-metal heatbreak and reuse the cooler and heat block from the stock hotend, in case you still have those.
