I'm talking about sonic's old boost. If you got boost-grabbed, you always wound up at the ledge.
Ah, ok.
Given how much Peach depends on the C-Stick for angling Side Smash and for turnip combos, I'd have to change to a second control set every time I go to G&W, which might not be well-received in Netplay in terms of taking up the extra time.
As long as you have good timing, you don't need the tilt stick or quick movements to pull off sliding dtilt or sliding grab. All you need to do is rotate the control stick down until you're ducking, and once you duck, press the A or Z button with your other hand.
You might also be able to do sliding jab. That requires letting go of the control stick immediately after ducking, but at least letting go is relatively easy. A frame or two after letting go, you can start tapping A to jab.
Sliding dtilt is the easiest option to hit with. However, it sends them at a low angle, which makes follow-ups hard. Onstage, they may be able to tech, and offstage, G&W won't be able to chase at full speed.
Sliding jab is a bit harder to hit with, but not by much. It doesn't combo into anything, but it's safe on shield, it beats spotdodges, and it can rack up damage.
Sliding grab actually requires precision; about as much as sliding down smash. On the plus side, it's a grab, which means it ignores shields and leads to any number of follow-ups, but since G&W has a very low grab range, the opponent can easily hit you on your way in. Try to condition your opponent to expect dtilt or jab, and once they've learned to shield, mix it up with a grab.
Should I just stay away from ledges when playing against him?
That certainly helps. Onstage, dthrow just puts you on the ground, leading to a tech chase situation.
I should also note that the gif is misleading because Samus didn't meteor cancel. The throw is definitely meteor cancelable, which means that no one will have any trouble recovering until very high percents. However, there is the danger of G&W following up with dair, so if he goes offstage, jump to the side and/or airdodge.

This is kind of getting off-topic, though. Maybe we should take it to the G&W character forum.
To get back on-topic, here's a request: remove the "spin control stick to glide" input. I'm trying to learn Charizard, and sometimes when I change my mind about what aerial to do, I start gliding instead of doing any aerial at all.
If spinning the control stick started a glide at any time (not just after a midair jump), I'd approve. But if you have to midair jump anyway, you may as well just hold the jump button.
