They are all pretty much the same. Gorilla makes the best tents but they are very expensive,if money is not the limiting factor than go for them. I have their lite line and the poles are way too thin, and I think they have discontinued that line. My ac infinity's poles are nice and thick,and the cover material is thick and durable. I've taken down and set up my 3x3 tents 4 times the last year they are holding up fine. I really like my cool grows 3-in1 tent though its on the cheaper end. If you don't want to spend a ton of money. i would try to find a deal on a random tent. i bought a "off brand" on sale its the groworld. 4x8 for around 120 usd which was an awesome deal. had the thick poles like the ac infinity but the outside material and zippers not as good. has been holding up fine aside fro the drip tray at the bottom has becgan to separate from dragging pots on it but I've had it for a year now and happy with it. i did not like the ipower 32"x32" tent I originally got for drying. it was overall very cheaply made and not the cheapest price. Havent tried Marz Hyro or Spider Farmer but they look to be pretty good too. I'm sure there are many more manufacturers I don't know of that are just as good. AFter owning all of those If I had to buy another tent I would go cheap as possible. i do like how the gorilla tent open all the way,but takes some getting used to zipping up. I haven't been too concerned about light leaks because I have my tents I the basement and I keep my flower tent and veg tent in separate rooms. if you are worried about light leaks do not buy the cheaper tents they tent to have more light leaks but any grow tent is going to have a few.
