I've heard good things about OUTEMU Sky, but I don't think they're in the same league as Zealios.
The other go-to for tactile in 2019 are Holy Pandas. Now, I know they are a meme switch, but they are actually more rounded in tactility than the Zealio, from what I understand. A little close to MX Brown, in the sense that there's a more rounded bump. So the tactility might not be as jarring.
But the situation with these is bad: you either get flawed (poorly lubed) HPs from MassDrop, or try to construct your own. And MD doesn't seem to be providing the Halo Clears anymore.
What are considered the "good" tactiles in 2019? Zealios, HP, maybe OUTEMU Sky. People still make Ergo Clears, but I don't see them much.
Lots of people miss the V1 Zealios. I loved the 67 gr, but wasn't ready to build a custom back then.
