It's clear that Maretti plays better.
To judge the strength of the players, you need to win against them; otherwise, it's just envious whining. As far as I know, Navukhodonosor - Captain hasn't beaten either of them. I, for example, believe that their skill levels are quite comparable.
I played 4 games against Maretti and 7-8 against Britva. I think it was more difficult to play against Andrey. (Just my opinion, of course).
Все в ней нулево и кукольно.
