It was nice of you guys to invite us over for discussion. Now for the matchup of the manliest character in Brawl vs. the least manly character in any Smash game ever (I'm really sorry about this, guys. Glad you're coping with it well)
For specific moves, you want to watch out for Dtilt (our good range option), Ftilt and Dash attack (powerful options) on the ground, and every aerial plus aerial Wizard Kick (it trades hits with your Uair when hit with the right timing) in the air. Ganondorf has a very adequate aerial game, and a good player is going to utilize it whenever he can. As for specific strategies, a Ganon player can easily bait a missed attack and hit you with Flame Choke, and with that comes guaranteed follow-ups or possible chaining of Flame Chokes (Pit's GUA is slow and moderately easy to powershield with the right conditioning). Therefore, always watch out when you decide to attack Ganon.
Dtilt outranges our whole moveset except Arrow and Angel Ring (I think), although both are slower (AR by only 1 frame though). Juggling Ganon really isn't that hard as long as you watch for what he's doing. A favourite technique of mine is an empty SHFF or SHAD fakeout into pretty much anything.
When it comes to Flame Choke, Ganon can only hit you with jab if you simply stand up (at least according to the chart on the Ganon boards, it might be out of date). I'm pretty sure it is, and I think buffered Dtilt is also guaranteed. Very rarely use get up attack, it's probably the most telegraphed option out of a choke, and being predictable against Ganon is BAD.
Pit has a chaingrab sequence-Fsmash that puts Ganon from 0-60. Considering Pit is pretty lackluster at killing, it's not that game-changing, but definitely an advantage. After that percentage, Pit's grabs don't really accomplish anything. You can be liberal about your arrows, as Ganon is very, very slow, but his Dash attack can go through your projectile unsafe zone fairly easily.
Pretty much spam arrows until Ganon starts to get close, then just run away as repeat.
Being really, really, really, really, really gay. You probably get that from everyone at this point, but Ganon mains have no tolerance for gayness. Sadly, we can't do much against the gayness either, so use every bit of it that you can.
Can't emphasize this enough. As long as you keep your distance, Ganon can't touch you, since the only approach that really gets through arrows is Dash Attack. However, I find planking to be fairly ineffective vs. the Dorf. The risk of a Dair spike just isn't worth the reward, and you can do much more damage on stage spamming arrows.
Ganon, more than likely, wins this matchup in the mid-range department. His Dtilt outranges your moves, Ftilt has a great amount of priority, and Dash attack has great kill potential plus decent cross-up potential.
Can't argue with this. Best to just back up or move in at this range.
That being said, once you get into close-range or out into far-range combat, Pit pretty much ruins Ganon's day, so your key here is to either camp him really hard with arrows or get really inside his space and jab/grab to your heart's content. Personally, I would prefer the latter, as anyone with patience can deal with camping, but Ganon's shield options are simply horrific.
Makes sense. Personally, I prefer camping, since there really is no risk to Pit as long as you stay far enough away. And frankly, that's not too hard.
I usually just suggest with whatever you're comfortable with, but if I have to say something... FD?
FD is good for Pit. RC also works well, but the Ganon will probably ban that. Yoshi's Island: Brawl and Brinstar are 2 stages that come to mind as being places you probably don't want to face Ganon, although they really don't change too much.
For a numerical ratio, I will also list
75-25
+1
As a final note, I have some videos that can help you further dissect the matchup. I don't know how active Vex is in Pit discussions, but he knows a lot about Ganondorf and how to fight him. Yes, they are friendlies, and Vex refuses to time me out for some reason, but he was serious in playing these matches:

I hope the serious comment was a joke. Most Pits don't wait until 193% to start using arrows, lol.
