Gateron Baby Kangaroo Tactile Switch

If you've only ever used a Cherry Brown, or any of the typical "brown" tactiles, the BBK is a nice refreshing change for your fingers. The bump is distinct, not sharp (like a heavier tactile) so it's a great experience. Not too loud, but a good solid sound. The pre-lube is consistent too, across all 90 switches I've used/installed.
The spring is strong, but not overwhelmingly so.

While these are now a couple of years into their life cycle, they are still a solid investment and worth having if you are new to tactiles.

One of the best tactile switches!

I love these switches. I have them in a Keychron V1 and I just put them in my Neo 65. They feel and sound beautiful in the V1, though they are a little loud in the Neo but that is likely the FR4 plate at work. My favorite tactile and it's not even close.

First tactiles and i love them, cant wait to put them in my neo70 that i ordered too.

So full disclaimer I have these on a pre-built board called the Halo65 by NuPhy. There's lots of good stuff about this board, but I've taken the time to put these switches into different boards and always had the same similar typing experience - it's a very crisp switch. Rebound and feedback is good, so great for typists like me who are more heavy handed and maybe not the most accurate, so it helps with that accuracy. The sound is also crisp, it's not muddy, and there's a decent level of clack. Some people have reported ping - I've not encountered this so it's possible either my ears aren't attuned, or my batch have a decent amount of lube on them.
