NuPhy - Halo96

nuphy halo96 is very good

The best keyboard for Starcraft is Nuphy Halo. Clem and Cure use it. It's good because there are no gaps between the function keys. 

I don't think that fits in your criteria in term of switch and/or size but I had a Nuphy wireless before and it worked with no issue at all (although the battery on it isn't great, had to charge it like every week, sometimes more). I've switched to an 8bitdo keyboard now, same, works no issue out of the box but this one has a beast of a battery...I think I've charged it maybe 4 times? And I bought it in october last year.

MX keys mechanical is good if you want a low profile board. I tried nuphy and really wanted to like it but it wasn’t for me. Still would recommend, it was very high quality and a very nice keyboard, we just weren’t a match. My daily drivers now are a royal kludge S98 for my work computer, and their southpaw version L98 for my personal computer. The pros are it was the only mechanical southpaw I could find that was reasonably priced, cons are that it doesn’t play well with Mac’s.

For typing feel exclusively, the best is lofree flow. I am selling my Nuphy because of this despite the flaws with lofree.

I think the Bluetooth connection isn’t great. That’s the major downfall and takes a while to wake up. So I end up having it wired the entire time and that’s fine for me. I still think it’s great. If you want a better overall version except it’s not aluminum then the kickstarter lite version is the one you should get.
