is this guy as strong as paul anderson? is he stronger than that one lithuanian guy?
Paul Anderson was a beast, the training methods of his era weren't on par with those available today.
As mentioned, it's hard to compare Anderson with Reza, because Reza obviously blows Anderson out of the waters in the Olympic Lifts, but Anderson had shit technique, but his strength in other areas was crazy, although some of those claims seems a bit exaggrated.
Anderson was a dominant in his era, Reza in his. I'd say Anderson may have the slight edge in raw potential, but potential is the thing you usually never gets to see.

The comparison between Reza and Savickas is interesting, and fair.
Savickas has loglifted 440 lbs, and also done 900+ lbs in the squat in a powerlifting meet (600+ lbs bench, 880 lbs deadlift).
Reza and Savickas have different qualities, it's just a matter of deciding who's the greater champion IMO.
I can't honestly decide, I am a big fan of Savickas, but Reza is just god damn strong.
