Depends. Every bike will be a new choice. In the end, probably doesn't matter.
But let's not fool ourselves. Restoring a bike "to like factory new" is a fallacy unless you are using the same primer, paint, chrome and decals from 50 years ago. All you really get is a new-looking bike. Nothing wrong with that either.
way back when bikes were refinished for just
‘race” transit wear, the peroblem was always to me- how many components get replaced to make the reassembled whole look good.
blemishes like scratched levers, worn taps, straps , saddle, just stick out.
