I have similar result with Fuso and Nagato, both at 70k avg damage per game and around 3k avg xp per game.
But i have to say that i like Nagato much more because you can go upclose and let those secondaries fire up stuff. Also it feel bit more sturdy than fuso. Havent suffered as much citadel penetrations in it than in fuso.
Also i have to state that With nagato im often up at tier 9 games, and with fuso i think i never got past tier 7.
Both ships are good in their own respective tiers.
