I think you might be looking at McFarlane through rose-colored glasses. They had more than their fare share of "QC problems", they make Hot Toys look like. . . well, McFarlane had a lot of problems.
Oh yeah, no doubt, but you can't deny their sculpting and painting was so much better 10 years ago than it is today. I mean even the prototypes for the Walking Dead figures have looked bad (well, except the very first comic ones that were just statues without the crappy articulation chopped in yet). QC breakage issues aside, they were amazing 10 years ago for the price point and for what they were.
