We have another thread about this... I'm pretty sure we do.
Anyway, the other differences is that Falco's attacks are generally more powerful - I have data to back this up, though. Air game-wise, he has three powerful moves and one that's tricky for killing, but good for combos. Bair, Fair, and if you can pull it off: Dair, are really powerful, especially Bair. Fair is generally used for racking up damage, killing, and gimping - it was awesome pre-1.04 where you could fast fall and drag people down in a semi-spike.
On the ground, Side Smash is a powerful kill move, but it's slow - slower than it was in Brawl. It's still usable though with good timing and because it has good coverage - I think it's about a 90 degree coverage of Falco's head to Falco's front. Down Smash is fast, kills, and covers Falco's sides. Up Smash is more combo-orientated, but it can kill, later on. It's like Brawl Wolf's Up Smash in function.
Tilts are all good with Side Tilt being a great spacer since Falco sort of does a front kick which covers more range than Fox's roundhouse and well, Fox's a bit short than Falco so, Falco has more reach. Up Tilt is great for combos and it lasts for a bit compared to other attacks. Down Tilt kills and setups combos since it's like a launcher. Jab combo is a jab combo, so there's not much to say.
Reflector shoots forward giving it more range, but it lacks the ability to stay in effect like Fox's Reflector. That said, since it has more range, it can work like an interrupter and a combo setup since you don't have to rush in close like Fox. I think it's a great move since it spaces and interrupts safely and quickly. It will interrupt basically anything without super armor along with being able to reflect - it can cancel Din's Fire right when it explodes, but it's better to run or shield it since it's requires tight timing.
Fire Bird is multi-hit and slightly shorter than Fox's Fire Fox since Falco already has higher jumps. Falco Phantasm can spike while Fox's can't. Blaster is another interrupter, spacing, and combo move - something where you can hit three times with it and lock an opponent in for the three shots. Sure, Fox can rack up damage, but Falco can stun people.
In short, Falco has better spacing and interrupting tools than Fox, but lacks Fox's speed and I'm assuming DPS. Falco will hit hard, but sometimes a bit too hard where you can't follow up - he can hit just enough where the opponent is off-stage and can still recover because he didn't hit hard enough to push them pass the blast line. Fox will hit more softly, but if he can rack up a ton of damage, you're screwed when he lands a kill blow at 200%. Falco's also slower, as noted by @

, but jumps higher; Fox is faster, but jumps less high. Like in past games, Falco horizontal moves deal more damage than his vertical moves - it's really noticeable with their Up and Side Smashes and Wolf was supposed to complete this by having a strong Down Smash. So, Falco is to Ike as Fox is to Marth.
Oh, and one more advantage: Falco doesn't have an annoying voice.
