Switching from aquafarm to Bubblebox (Brummy Bubbler)

Hi, im looking to move from aquafarms to bubblebox's also known in some places as the brummy bubbler. Has anybody had any experience in switching from aquafarms to the bubblers? Every shop i have gone to has told me that the bubblers are the way to go, but with the bubbler being more expensive im guessing they might be trying to make sale. In regards to yield, am i more likely to get more yield by using a bubblebox, i know it all depends on strain etc but has anybody noticed more yields from any strain whilst using the bubbler? What advantages does a bubbler have over an aquafarm? thanks

Brummie bubblers are cheap 49 pound all in,massive yields
