While after Prost it's very hard to choose, then it's time to take a look at pros and cons of a number of drivers, who are roughly on a similar level.
Pironi. Likely to win the 1982 championship without accident. Quick in 1980, but error-prone. Got outperformed by team-mates in the beginning of his career, but you could say fair enough about that. Then again got well outperformed by Villeneuve in 1981. Career ended early, so we didn't get to judge him fully.
Arnoux. Looked very fast in qualifying in Renault. But... how much of it was the supremely quick albeit unreliable car? Because he didn't proceed to outperform Tambay and wasn't completely convincing against Alboreto. After that dropped off.
Laffite. Very impressive in Ligier for a few seasons, particularly his 1981 campaign in which he competed for the championship. Then again he didn't have a team-mate in Ligier for a few years, Depailler and especially Pironi troubled him, and he fizzled off, when he went to Williams. Nowhere near Rosberg. Then again age was a decent excuse by then.
Depailler. Overshadowed by Scheckter. But his best period might have been late 70's, prior to the accident. Looked good against the very highly rated Peterson at the time, even more so against rookie Pironi.
Cevert. Looked like a good #2 driver to Stewart. Anything more? Well, then again Stewart was the elite driver on the grid at that time, so in context that's not too shabby either.
Tambay. Looked okay in Ferrari after getting the call-up as a substitute. Solid 1983, solid in Renault against Warwick. But other than that? Hard to say.
Alesi. From a different era altogether than these guys. Showed flashes of brilliance at times, but was inconsistent and ultimately fitted into the role of a "good but not great". Not among the best of his era, but somewhere after these guys.
Behra. He was way before any of these guys. Would say only as much as that while he wasn't among the benchmarks of the field (the likes of Fangio, Moss), he seemed like one of the better ones among the rest. How does that compare I don't know.
Then after these guys I have no idea, how to pick between the likes of Trintignant, Beltoise, Jarier, Jabouille, Panis, Vergne, Grosjean. Everyone had the odd flash of brilliance, but that's it. You could add also Servoz-Gavin to the list, although the sample size for him is way smaller than the other guys.
