I have two Ajazz K870Pro boards - one with Outemu Silent Cream Yellow tactile, one with these Wuque Studio WS Silent Tactile. (FWIW, both board have been modded with tape and foam).
These Wuque switches have a very obvious tactile bump, are much quieter than hand-lubed Gateron Black or Reds.
The tactile feel is more positive than the Outemu, but the Outemus are quite a bit quieter still!
