I've never had any complaints with a Nuovo/Super Record's shifting performance. The feel in friction shifting is a little different from a modern slant parallelogram, but either seems work great. I think the only real difference really is the slight overshifting one needs to do, especially on downshifts, with a S/NR, but that quickly becomes second nature and you can get any gear anytime with a little practice. I have a very modern Shimano rear derailleur on an off-topic bike I use in friction mode and I honestly have to say it is not really significantly better shifting with an old-style non-ramped freewheel than a vintage Campy unit. It does feel slightly better/more positive under load with a ramped cog casette but I suspect the ramped cogs in back probably account for most of the difference in shifting when I use them rather than the derailleur itself, though I haven't tried a S/NR with the ramped cogs yet.

Actually I've discovered a Nuovo will shift beautifully and effrtlessly even across a new 14-28 Shimano twist tooth FW. I guess I'm just not critical enough about shifting performance, that's the only explanation I can fathom why people seem to not like shifting vintage Campagnolo.
