Personally, I favor original paint bikes as most and would rather have a 5 condition over restored... lesser condition and I prefer restored, if correctly done.
Some bikes are so rare that your choice might be restored or nothing.
I suppose my restored bikes are not full boogie concourse/competitive presentations as I use best original plated parts.
Why?
Because plating is expensive, is often destructive to the piece, and with original chrome/nickel finish, there is a connection to the past originality. That and I just don't like too shiny as it conveys new.
To answer your question, it is preference, but from a financial perspective, which underlines any hobby, it is best to pursue best condition originals down to the rubber.
