Like Marchisio, but 3 times more productive (how often you seen Marchisio do the assists Hamsik produced for Cavani this last league game?), so yeah I could see how you could say that, deeeeeerp
He is kinda bland to watch, and dissapears a bit at times, but he is riiiiiiiiiidicolously consistent in his productivity. I choose him over Lavezzi purely on the fact he is a midfielder but is more effective or at worst as effective as Lavezzi in scoring and assisting. Playing further down and being able to be used in more ways just makes him tactically more useful.
But most importantly, I just find him to be way more intelligent player then Lavezzi.
