Airhead UFO or Sportsstuff Bandwagon 2+2

I am wanting to purchase an inflatable suitable for kids ages 5 -14 years of age. We have a pontoon boat with 135 hp motor and a yamaha jet ski to pull the inflatable with. Would you recommend either of these towables, or something else. I already have a 2 person stingray from Airhead, and had Super Mable which everyone loved, but has died. Sincerely, Jennifer
