I used pad for my first three competitive fgs (Tekken 3, GGXX, MK9) then switched to stick after ~ seven months of getting frustrated with them for injustice. I was instantly more comfortable, winning as much or before after only two weeks, and at three was pulling off harder combos (ZATANNA) with much less practice. I think any competitive player should try pad, stick, and hitbox for a while each to see which they really gel with. I tried keyboard for a while back in the day and never got comfortable enough to do basic combos, never mind win matches. Once I get me a dual modded stick I'm going back through every game I own to relearn and get nostalgic.
