Your tester might have Zealio or Zilents in it, those also had their moment in the sun. Really expensive though.
Edit: Actually, there are other switches to watch out for. Assuming that this is your switch tester:
https://drop.com/buy/kbdfans-all-in-one-72-switch-testerPay attention to the Box White, Jade, and Navy. They're clickies, not tactiles, but they use a different mechanism for clicking than the click jackets that Cherries use. Click bars are generally considered to be superior in just about every respect.
The Box Royal is a tactile with a very strong tactile bump. So strong that most people don't seem to like it very much, since they can't help but bottom out after getting past the bump.
The Hakos are designed by Input Club, and are tactiles with shorter springs than typical, and stronger than typical. With the Hako True having the strongest spring. They're intended to prevent you from bottoming out.
The Hako Royal Trues that I mentioned above are a combination of the Box Royals and the Hako Trues. The result is a distinct tactile bump, with a small gap before bouncing off the spring. There is a Hako Royal Clear on that switch tester, which is the same thing but with a lighter spring.
