OEM Brake Rotors...which one?

[MSDGN]

I want to replace the rotors on my 87 T with stock GM OEM ones...I found 2 on RockAuto but not sure which one to get...these were listed under High Performance:

ACDELCO Part # 18A87A {#19287184}
ROTOR,FRT BRK(W/HUB) ; ACDELCO ADVANTAGE; 2 DOORS

ACDELCO Part # 18A87 {#18027687, 19174913} replaces 18027687
ROTOR,FRT BRK(W/HUB) DURASTOP; 2 DOORS


...appears one is ACDELCO ADVANTAGE and one is DELCO DURASTOP...the DURASTOP
costs more...so what is the difference between the two?...one better than the other?

i'd guess that one is made in China, the other is made in Taiwan..
