Real Rubber Hoses... beware of the marketing that uses the word Rubber to market it, and then in fine print somewhere, it says something along the lines of Rubber composite, or rubber synthetic...
I'm wary of anything else that is NOT rubber.
Another thing is if you physically need to move the hose, I'm a huge fan of expandable hoses like Xhose and similar. Don't expect them to last a long time though. Rubber hoses are heavy and I have a few around the house that have a permanent home in their reel, and if I need more than 1 hose (kids playing with more than 1 sprinkler/water toy for example), the second hose I always bring out is the expandable ones. Light and easy to move around. I highly recommend both!
