I found AC09/IC10 to have very odd head models, that detracted from the overall look. It doesn't really impact my overall view though, the graphics are at the very least at the point of not being a weak point. AC13 on the other hand would be let down by the graphics even if it did play well.Actually I sort of agree, the graphics are really good but they do look a bit cartoony, it sort of reminds me of cricket revolution in a sense that the field and everything else doesn't look that detailed and small compared to the batsmen etc
however I'm not saying they're comical like cricket rev, for example the Ashes09 IC10 series graphics look a bit more "serious" in some aspects, but we still haven't seen enough of BA and tbh it's not that big of a deal.
I don't think any game has nailed the look yet, but these are certainly not rugby players like EA's old models.
