Valterra Dominator Sewer Hoses - are they worth the money?

Need to replace my old Wally World stinky slinky hoses which have developed small pin holes - looked at Rhinoflex and Valterra Dominator hoses and fittings - prefer the Dominator series as they have universal connectors and have a 2' compartment hose. Looking for comments, pros and cons, on these two products - also, where's the cheapest place online to buy these?
Thanks
