Are Skaven competitive?

Hey everyone. I just bought the Warpspark Spearhead because I wanted to try an army that played differently from my Slaves to Darkness and Blood Angels. I'm not super competitive and will be playing Spearhead against Bonereapers and Seraphon mostly. That being said, I don't want to lose every game and I've read a lot saying the faction isn't in a great place.

I was just wondering what the state of the army is right now? I really like the tricksy playstyle and the all the weapons. I'm just unsure how to win when I look at our stats.
