I haven't gone crazy big but have used up to 11litre pots. I think a lot of people just think big pot means big plant so more bud. Not always true in fact I prefer my 6litre pots with coco. Feel the plants grow a more manageable size and root quicker.
End of the day you can only produce based on the lights so worth working it out by that and your plant numbers. If your growing under a 250w and have 3 plants, your aiming for gpw which works out just shy of 9oz so call it 3 per plant. Can easily achieve that from a 6 litre pot so going any larger imo is just wasting time waiting for the larger pots to root. So when I am deciding on pot size I try to base it on how many plants I'm running under what light.
