Generic braided fuel line and regulator, worthwhile buy ?

Myself as well as every turbo ls guy that has 2 nickels to rub together have had good luck with the evil energy ptfe stuff. So far I have had zero issues with it. Good fittings, assembles nice, and I had zero leaks. The entire car was done with this stuff. -8 supply -6 return y block at the fuel rail, and -6 trans lines. Have had over 100psi on them and zero issues.
