I can't imaging a slightly rough bottom bracket (or hubs) will have any noticeable effect on a non-competitive rider on a heavy bike. It may cost them a few seconds overall but so what. Reducing the bike weight by a few pounds would be more beneficial.

That said, good bearings and components are smoother, lighter, more durable and better operating. Good components shift better, brake better and steer better.
