Classic Abom war the version that beat Hulk down in three punches, something even the likes of Thor couldn't accomplish no matter how many times he tried. The only other time Abom was at those levels was when he was powered back up by the Galaxy Master. All of his other appearances were where he was depowered, including his fights against Surfer, Wonder Man, etc.
I'd probably give Supes the majority as well, but I wouldn't give him 10/10.
I'd take Protex, Jay Garrick, Firestorm, the Traitor, and Hourman Android.
Traitor for the Doomsday like adaptive and growth factor.
Protex for the general top tier superstrength.
Garrick for the speed.
Firestorm for the matter/organic manipulation.
And the Android for time manipulation.
I'd own anybody else.
