When buying a water hose, learn how much pressure it can handle before….

Bursting. 50 pounds per sq. inch is a good strength. The wider the hose, the more water can flow through it. 1⁄2” is fine, but 5/8” is better. Rubber will withstand weather better, but the important thing is that whatever the material, it be reinforced with a mesh layer. Look for one claiming to be kink resistant.
