One that's not accidentally jumping nearly as much as I was before I switched that option off.
Ahh, so one that sacrifices the incredibly useful Spin Attack Out of Shield because he hasn't taken the time to learn the push the control stick gently.
I used tap-jump-off for a very long time because it IS frustrating to accidentally jump, but when I started playing Link (and when I started playing Melee so I could try Samus), I realized it would be really beneficial in the long run to just learn to up-tilt without jumping. I still do up-airs with c-stick though.
Besides, the same amount of gentleness is required to down-tilt on a platform, so it's good to learn. It's only about as hard as learning to short hop with Fox or Samus. Which is to say it's pretty challenging when you start but it gets easier. Wavedashing is like that too. And a lot of basic techniques.
Link's spin attack out of shield is really great. If someone pressures your shield and lands behind you, you can still hit them really hard, really quickly. It's good for killing high percent people who are trying to pressure you. It's good for just being a scary option that makes people scared.
In Melee, Samus's up-B out of shield is practically her sole response to shield pressure, aside from wavedashing out of shield.
