Gorilla tents are fantastic tents, great zippers, height extensions, lots of oversized ports, and super durable.
Apollo is about a third of the cost, uses the exact same poles and corners as far as I can tell(even using the same little blue stickers with the same letters on them). But it will have minor light leak on the corners, so you have to tape that up if its in a bright room, the 6" ports are exactly 6" so getting vents in and out is a pain, and the zippers will wear out after a couple years.
Personally, i just use apollo now, and will replace them as needed, but I certainly don't regret the gorilla 4x4 purchase.
