Hogs are nice planes except for that acre sized plate on the canopy. With view keys its relatively easy to map your views for getting around it, but IMHO in TIR its very easy to lean back and get your head stuck behind it so you can't see anything behind or above. I'm pretty sure it wasn't quite that big in real life and not all variants had them.
Once you get around that, they are like most planes in the game, they are pretty good to fly and with the exception of the -4, not that hard to kill if approached from their weaknesses.
