Both got a lot of hype, but neither lived up to it. At their respective best who was better? At their worst who is worse?
Both have paltry competitive records
Apples and oranges. Kovacs has vastly superior genetics for size and strengh than Fedorov - actually, more than anyone else -, but Fedorov has much, much better bodybuilding genetics. I can't believe you people put Kovacs and Federov in the same sentence

Fedorov is clearly a vastly superior bodybuilder: he finished third to Ronnie and Jay once, for fuck sake! Conversely, Kovacs tanked at the NOC, one of the minor pro shows. Can you even compare the two as far as bodybuilding goes?
However, even though Kovacs has arguably the worst bodybuilding genetics of all pros, he is an absolute titan when it comes to size and strengh genetics. No Human has ever been close to Kovacs in sheer mass and strengh. Here are Kovacs lifts:
-One arm dumbbell row - 300 lbs dumbbells for 4 reps
- Flat dumbbell press - 300 lbs dumbbell for 6 reps
- Front military barbell press - 440 lbs for 12 reps
- Barbell row 528 lbs for 8 reps.
- Lateral raises - 100 lbs dumbbell for 10 reps.
- T-bar row - 352 lbs for 6 reps.
- Deadlift - 810 lbs for 3.
- Leg press - 2700 lbs for 15 reps.
- Squat - 850 lbs for 2 reps.
Hope this helps!
