Really depends on my immediate needs. It can be very much worth it to upgrade all your newly-obsolete units up to the best troop type. For instance, converting hordes of musketmen up to riflemen if you grab rifling early is pretty much a game over for any civ next to you, where it would normally take many many turns to produce riflemen the old-fashioned way, at which point the AI may have caught up and produced riflemen of their own. Alternatively, it's good to upgrade defensive units in difficult circumstances. If, on the other hand, I'm not too pressed for time, I usually prefer to just produce the units normally and keep the science slider running full blast.
