aftermarket ones are better, some of them are considerably better..
I would take a set of comp lifters any day over the factory ones
and I would take Morel racing lifters over the comp lifters...
the question become how crazy of a cam, and how high of an rpm are you going to spun the engine.
under 6800 and a cam that fits under stock heads with no valve reliefs?... stock Gm lifters are fine
start getting into big lift, large lobes, or higher than 6800 rpm, you need to step it up..

No I have a lazy lifter I think. Tap comes and goes as it pleases but is loud when it decides to tap. I did ruin a rocker and a valve stem were the rocker rides so I already have to get that fixed. Your rite. I may have torn the cam up. I guess I'll know when I get it apart.

Aftermarket lifters are alot better, if you buy the right ones. Your application probably doesn't require them though. I would recommend the OEM LS7 lifters for this type of build, they are very affordable and a major improvement.

What the heck would cause that??
I must say....A lifter's anatomy isnt that complicated (spring, piston, and cup).
What ever happened to that lifer, I doubt it was because it was a "stock lifter". I know the LS7 lifter's skirt goes all the way around, but many of Comp Cams and others use that exact design as above.
