I’ve owned RS and WB.
My RS 750 lasted 5 yrs before the seam was about to bust. RS customer service didn’t budge an inch to try to compensate or give any type of discount for another tank.
I’ve had my WB 330 for a year now and love the aluminum framing, customer service and the euro bracing. I also like the armored corners so that the beads of silicone don’t get damaged as easy during routine cleaning of the glass. As of now, I’ll only be buying WB from now on. Did I also mention I have a WB 25 and 15?
