I've noticed some apartments that use both for water supply to faucets and toilet cisterns.
I understand that the braided hoses are rated for higher pressures, but how do they compare in terms of durability at typical static and dynamic pressures?
Is it correct to consider the EPDM layer in braided hoses, by itself (minus the support of the stainless steel braiding), to be equivalent to a rubber hose in terms of pressure resistance?
Durability - I have often seen the stainless/chrome plated hose breaking up after a few years... this is where the hose splits along the seam of the hose... This will not happen with the braided hose due to the fact that you have a netted sheath. Also. the braided pattern is more flexible than its counterpart.
Cost - This hose is substantially cheaper than the corrugated style hose.
Ease of manufacturing and assembly: this hose can be crimped during assembly, the alternative is to use more complex and expensive screw clamps to assemble the unit.
You will probably also find the regular stainless braided hose like this:
I would expect more water to flow unless you have extremely low water pressure. You have a 3/4" line and all the water pressure of either a municipal water system or a water pump. Splitting that into two lines will not likely double the flow rate as there is a pressure drop, but it should increase the total flow rate considerably. I would expect it to almost double, but not quite.
This would be easy to test with an empty bucket. Time how long it takes to fill the bucket with one hose on and then with both.

The braided stainless steel flex supply lines are just jacketed with braided stainless. The jacket is there for appearance and perhaps resistance to incidental contact damage, but has nothing to do with the pressure rating.
In general, rubber hose is not used for faucets and cisterns; the hoses (whether jacketed with braided stainless or not) are commonly reinforced PVC (at least in my area, anyway). The washers are often EDPM rubber...
