as the other guys have said I prefer buckets although it wasn't always that way, originally I used to use demijohns (carboys) but u cant beat the flexability of a bucket for cleaning and ease of use, it just makes everything so much easier, to clean and to use, its basically your best bet.
PS make sure its food grade if its plastic, non food grade plastic leeches flavours that aren't good for wine, what ever source u get your buckets from.
