Until very long APFSDS ammo became a thing, angles of armor were a real thing. And round shape makes structure more rigid and also more stable against shockwave from large blasts (including tactical nukes). Now it doesn't really matter, but this tank is from 50-s.
Sadly, it died with other heavy tanks when Khruschev came in real power. He launched man into space but made serious damage to tank and aviation industry (especially attack aviation) because of his love of rockets.
