They would all have to be great towers and great service to beat the bunch of guys at MONSTER TOWER, When I was installing the tower I needed longer bolts. They sent them to me for free within 24 hours. Had a problem with a rack, replaced within 48 hours, at no charge.
Used the Tower on my Runabout for 2 years, Took it up and down twice every time we took the boat out (LOW BRIDGE) and never had an issue with rattles or any noise.
Hard to beat these guys.
They are all about service.
