Comparing materials to each other is very difficult because there are so many different formulations and their performance vary widely based on the specific formulation.
For example, rubber hoses tend to be the heaviest, hence why PVC and hybrid hoses have been created.
Exception- BluBird hoses are completely rubber, but are the lightest hose on the market.
PVC tends to be stiff, but there are plenty of examples of flexible (even in cold weather) PVC hoses.
So instead of looking at specific materials, start looking at specific brands that offer good hoses.
Goodyear has rubber and hybrid hoses (Tekton also sells these under their name).
Flexzilla is also a great company with a variety of different hoses.
BluBird also makes some great rubber hoses that have the best performance in the cold of any hose I've seen. They are rated to be highly flexible at much colder temps than any other hose. I live in one of the coldest places in the USA and have a BluBird hose (the blue one for cold temp) that has been fantastic. I also have a BluBird Yellow oil shield hose that, while not as flexible as the blue lightweight hose, is still great and has better oil resistance. K-Tool also carries some BluBird hoses
Those are the companies I would look at
