This was 100% true for me until I actually found some I like just a few months ago; pretty much three all at once, and any one will do:
I’ve heard of other new / good stabs - but as long as I can find any of these, I’m good to go.
I was just about to make a post (or find a place to post) a question regarding the best stabs these days. Are there any specific stabs that would be better for a Bakeneko / Unikorn style build? I remember in the old days they’d recommend clips in but I think that was remedied by flipping the stab so the screw side could be away from the perimeter of the board? Any new meta I’m missing? I haven’t really built a o-ring gummy board in a while and planning to make one in the next few months.
The Stupid / Maiz stabs are clip-in, the other two use screws.
My only complaint about Knight stabs is I can never find them in stock. Still haven’t been able to try them yet, though the TX AP v4 stabs are generally pretty solid.
Any recommendations on vendors that are able to keep Knight stabs in stock?
I think the clear solution here is to buy a Seneca, harvest the stabs, and discard the rest. 
Honestly I just snipe the restocks - some vendors let you sign up to get an email when they restock, and that’s when I grab 'em. I know I got some from DiviniKey a while back - it’s true they never stay in stock for long.
Getting sucked into cool keycaps, but then rediscovering that I’m almost always happier with PBT blanks….
