So I received the Penguin switches and they're a bit less tactile stock with a more rounded tactile bump, compared to ergo clears with the 63.5g Penguin spring. At 89g with MX Clear springs, the Penguins are quite noticeably less tactile and rounder than stock MX Clears. Overall I wouldn't say they're an exact replacement for MX Clears if you're looking for the exact MX Clear bump profile, but if rounder and less tactile is what you want, then maybe it's for you. I also compared to an MX Brown with the 63.5g Penguin spring, and it's definitely much closer to Clear tactility wise.
You can see that the corner on the stem responsible for the tactile bump is more rounded on the Penguin (left) compared to the MX Clear stem (right)

It definitely has a sharper bump than T1/Koalas though (here's a Koala stem for comparison)

The leaf is noticeably less tactile than the T1/Koala JWK leaf. Swapping a Koala stem into the Penguin bottom housing significantly reduced tactility, and swapping a Penguin top and stem into a Koala bottom housing significantly upped the tactility. Swapping an MX Clear stem into a Penguin housing made the tactile event a bit more tactile and noticeably sharper.
