Personally I wouldn't stock up too much on one type untill you know if it suits your bubba. Maybe just a box or 2. Also they can have sudden growth spurts and can be too big all of a sudden when you're half way through a box. Keep your receipts JIC you have any unopened boxes so you can exchange for the next size up.
I've found snugglers to be quite good for the price, though the last lot I got leaked quite a bit at the sides. Don't know if that is an issue now as they have changed them bit.
I've used most of them from time to time and not really found there to be many differences except for things like the grip tabs instead of sticky ones.
