I can't comment on vintage blacks because i have never tried them, but I can comment on new (retooled) Cherry blacks, old (pre retooling) Cherry blacks, & Gateron blacks. IME the new retooled Cherry blacks are a tiny smidgen scratchier than Gateron blacks when brand new, but after breaking in & lubing they become buttery smooth just as good as Gaterons IMO. The old (not vintage) Cherry blacks were pretty scratchy brand new, but broke in like all Cherry switches to be fairly smooth. Lube helped a good bit with them too, but the new Cherrys & Gaterons would be superior even after breaking in & lube. The Gaterons blacks are very smooth even at the 1st key press & feel even better lubed but the break in is less of a factor, also they are noticeably lighter. So really after some use &/or lubing new Cherrys & Gaterons are essentially just as smooth as one another, with the Gaterons being more wobbly & lighter while the Cherrys are tighter & heavier.
The main difference is Cherry has tighter tolerances with how the parts fit together than Gateron does. Hence Gats being more wobbly on off center key presses, being smoother at 1st, yet not getting much smoother with use & Cherry having the exact opposite attributes. So I would say give the Cherrys some time to break in & lube them if possible. IMHO spending all the time & money chasing vintage blacks or even getting Gateron blacks & swapping them in really isn't gonna get you a better end result & most likely be a waste.
