Plus if he have an off flavour from a fermenter sample you can cold crash the beer for a few days. Rack to a keg. Force carb it and smash it.I asked this same question at the start of this thread... I don't reckon i could ever be stuffed with kegging until I'm living in a larger house and have more space, which given i'm in Melbourne is pretty unlikely.
It's the cleaning of the bottles that would be the biggest advantage i reckon
By not bottle conditioning to produce C02 you don't feed the infection and instead chilling it turns off all fermentation and the by products/off tastes cause from it.
