Benefit to Hog III over Full Boar?

Can someone tell me the benefits of a Hog III versus a full boar? From what I can read, the only major difference that would set the Hog III ahead would be the possiblity of more than 8 universes of ArtNet.

The Full Boar, on the other hand, has the 4 universes on board (expandable with the widget to 8) so I don't necessarily always need a DP,
USB drive, and ArtNet connector on board (so I wouldn't have to get a DP 8000 just to drive ArtNet). It seems it has the upper hand.
