Disc brakes are a fairly inexpensive upgrade these days, and do not have the brake fade drums will have after a little while. Disc are good from beginning to end, drum are good when new, but even half way through the brake shoes life cycle you can tell they are not responding as well. If I made a top 5 things I would add to a car to make it more road worthy, disc brakes may be #1. Drum are operable you just have two drive a little more pre-cautiously.
My experience with OEM parts and aftermarket parts is with fenders for a 1970 Mustang. We had 1 NOS fender and 1 aftermarket fender. I could have put the NOS fender on blindfolded, it fit that well. The aftermarket fender looked like a Mustang fender but that was about it. It didn't fit anywhere and had to be modified heavily to fit reasonably well. I would suppose they might be making them better now.
Had a old Chevy PU with front drums. Put new bonded shoes on it. A few months later, on the freeway, a blind old lady in a Caddy cuts in front of me and slammed on her brakes. I hit my brakes. The bond on one shoe broke loose, and a chunk of brake material got caught between the drum and the opposite shoe. The drum snapped, and I had zero stopping ability. I swerved onto the shoulder, and coasted to a stop. From then on, I would only buy riveted brake shoes.
