I chose bottles, but for me it all depends on the brew. With my EW Apfelwein clone, I kept it in primary for a while (12-15 weeks if i remember correctly), and I have some still in bottles from last spring..
I don't like keeping stuff aging in secondary mainly because it is easier to keep bottles stored and I like keeping my fermenters free for new batches
