Its almost impossible to avoid clipping on bright stars so I'd qualify that to say you should avoid excessive clipping on your target. And if you can get a reasonable exposure time without any clipping that's ok too.
Because I'm in a light polluted area I need to be sparing with gain so lately I've been capturing just RGB and not bothering with L at all.
