I've only tried Brown, 62g, Clear and stock Black springs in my modern Blacks and found the 62g to be the best.
The problem I have with Blacks is that they're linear
So I don't have a tactile reference of when they actuate. As a result, I bottom out on them with every press (since I have a pathological need to know the key has actuated I guess, so I make sure), so Clear springs feel too strong. If you can type on linears without bottoming out, I suspect Ghost Blacks would feel nice, but since I can't, I can't really say they're any better than stock. I suspect even stock springs would feel okay without bottoming out, but I find them fatiguing. So, for me, 62g springs and some nice thick, heavy caps feel best. I'd find 50-55g springs too light for my taste and probably would mistype with them.
That said, 62g ErgoClears are the only MX switch I actually use nowadays.
