I have had both.....very similar in size,style and performance....given the same power and pump setup
They both like a lot of power...as do most tunnels..
I like them both...you would not go wrong with either....It would come down to who rigged it and set up the pump
Tom Papp could probably give you the best answert on the differances..he has built enough of both...
