flex hose for new water heater??

is acceptable to use flexible hose to connect water pipes to a water heater. our new heater will be taller than the old and this would be easier. will it be as durable?

thanks for the help.

Corrugated copper flex lines, yes...
Stainless steel braided flex lines... I seriously doubt it...

Very much a local question. Some places definitely NOT. Here in California, flexible connectors are MANDATORY.

If your area allows flex, then you will find corrugated copper types, as well as the braided stainless steel. For some reason, I have noticed an unusually high failure rate on the braided. I can't explain that , because they are similar to the ubiquitous faucet supplies, which are very reliable.
I don't know if it is the larger size, the proximity to the flue pipe on a gas WH ( I suspect that is the issue) but I have seen way too many pinhole leaks, and will not use them.
