If you are getting routinely outcamped by Falcos, then you are playing this matchup wrong. Generally, Falco doesn't win this matchup by camping, he wins by getting a grab and keeping Snake in the air / off the stage.
Falco can shoot the grenades / reflect them, but Falco needs to hit you with numerous lasers to do any significant damage, while Snake only needs to land one or two grenades. The reflector is extremely punishable at the right range, as are lasers if you are at a mid range and power shield them.
Snake should have no problem with mixing up power shields, and yes even crouching for a second, to approach a Falco when he needs to.
If Snake were the exact same character but weighed half as much, this matchup might easily be 60:40 Falco. That's not the case, though, and Snake's weight combined with his amazing kill power / punishes on Falco give him the advantage, assuming that Snake avoids the CG, which he should be able to avoid more than half the time on most stages.
If you are both at 3 stocks and at, say ~50% as Snake and Falco is at 0%, Snake is easily "in the lead". I don't see how you can even attempt to refute that. Falco has the advantage IF he gets the grab and there isn't a 'nade about to explode to mess it up.
Falco has the gimp advantage, Snake has the not dying / kill power advantage. Therefor, avoiding CGs would generally put Snake slightly in the lead... and avoiding a Falco chain grab as Snake is not hard...
I don't really see how I'm "crying" with any of this, I already mostly agreed with the 50:50 consensus on the Falco:Snake matchup like 2 months ago on the Falco boards. I'm still swayed more towards 55:45 Snake's favor on most levels, but that's still a neutral matchup, so how am I "crying"?
