Aircraft grade stainless braided line doesn't last forever and when used in aircraft and some race cars it has a stainless date tag crimped on near one end to show it's expiration date.
The rubber hose under the braiding eventually dry rots and you can't see when that has happened until it leaks, if you wait or have the car long enough.

Some of the premade stainless lines that come with short headers take sharp 90 degree turn in the hose right after the steel case fitting and I've seen some that are slightly collapsed where they make that bend or turn going to the passenger side of the car. That could restrict oil flow.

Anyway, if it is high quality line like aeroquip and installs with no tight bends the stainless line is less expensive than the 2 OEM lines and should work fine with no worries for 15 years or longer on a street car.
There is not alot of pressure or resistance to flow in the scavange line, external oil thermostat, and oil cooler circuit... the oil filter element at the end of it is about the only restriction to oil flow it goes through.
