Character holds across recordings, yes. Same system, single change, controlled environment, is my preferred context. While a difference may hold a cross different systems, that's usually too many variables, particularly if you run across one, where there might be more synergy.
But I'm not a flipper, that is short interval back and forth. Imo, that's more likely to give misleading impressions than taking longer time with each. I do realize some folks don't have the time to take, much less live with components for weeks or months.
