I've used all kinds, swing top grolsch, 12 oz capped, 22 oz capped.
I prefer the 22 oz capped though, they take up less space, per batch. I dont mind capping though, but I have a bench mounted capper that is awesome.
Only thing I don't like about the swing tops, sometimes you miss a rubber seal that may have a crack and the bottle doesn't seal and you get an un carbed beer. Never had that issue with a capped beer.
