Military Affairs T55 vs T62 vs Slovenian M 55S Tank

This is a series of discussions of military hardware currently being used in the Russian and Ukrainian War covering weapons that are generally misunderstood.

Brian Berletic of The New Atlas is consistently down playing the Slovenian M-55S variant of the T55 Tank and states that it belongs in a museum. With a little bit of research one will find that this variant can kill a T72 tank. Is it any worst than the Russian T62 tank being used in Ukraine?
How wrong can he be?
