I like that I can choose which games to play first, so I select always all the games of only one engine at a time, quickly having his ranking. I cannot do that with Arena!
I like that i can customize every colour, font and layout of a superlative graphic UI.
I like that it doesn't restart again and again the same aborted game, like Arena does very often

I like that I can easy fix crashes, repeating the game.
I like that I have nice crosstables together with ELO and tech values about nodes calculated.
I like that I can choose between multiple stats.
...And this only related to what I'm using between huge BSG available features
