It depends how good the infighter is. There are too many fighters who just seek to maul in there with no real purpose. It's like any style of boxing. When it's done great (Angulo-Alcine a recent example) than it's thrilling to watch. When it's done badly (Froch-Dirrell comes to mind) it's the worst type of fight to watch for me. I will say that I'm personally more of a fan of seeing guys boxing at mid-range, but truthfully if I get to see a fight where all of the facets of the game are on show I will positively love it. It's why Mayweather-Mosley & Ward-Bika were two of my favourite fights of last year, because I got to see guys showing how completely rounded their game is.
