The first three guys you posted pictures of are all "on" (google for Stallone + HGH + testosterone, the guy in the first picture has this "swollen" look typical for roid users and the other guy is a former training partner of Schwarzenegger ... enough said).
Vicious is basically echoing what I believe, too - the guy in the last picture hasn't even outstanding genetics, but simply keeps a low enough bf ratio for some visible definition and has some muscle tonus. Am almost 100% sure he's clean and always was.
"The golden eagle" Tom Platz on roid abusers: "Most of them look like shit, and perform like shit".
An interesting interview with him - from 1988; he was 2 months off when the interview took place - how his performance decreased when going "off" (mind you, he's obv. a genetic freak as all IFBB or NPC pros are):

Quote "But taking chest as an example, while on drugs, I would work pecs for an hour; off drugs, I would work them only about 30 to 40 minutes. There was a time, before the Olympia, when I would do the incline dumbbell press with the 150s for 10 to 12 sets back to back, with forced reps to failure and I would start out with 15 reps. Now, if I can use the 150s, I'm lucky. If I can push out three or four reps for two sets, that's great."
