With spring weight accounted for, linearised blacks from a NIB AT101W and the Taobao NOS SKCL yellows feel more or less the same to me, and both are better than the SKCL greens I have simply due to the fact that those aren't super clean.
There are people that would tell you that the older housings are better or that tall switchplates make all the difference, but I don't really buy it. Best to use whatever's available in the best condition, unless you want rare/old switches for the cool factor (which, to be fair, if you're using linear Alps over MX at this point isn't all that unlikely).
Use SPRiT's springs at your preferred weighting if you're OK with his business practices.
