To the OP- Yes, really, they are that good. There are a bunch of things at a very high level in fighting games that you just won’t be able to pull off with the kind of consistency you need to be competitive against the best of the best. Pianoing reversals, charge partitioning, some of the more difficult and complex combos and super cancels in several different games, stuff like this will always cause you more problems on a pad, so stick is better if you’re ever going to get your game to that level, but to balance that out, you should ask yourself a few questions:
How long have you been playing fighting games with a pad? If it’s 6 months, then by all means pick up a stick and go back to basics and re-learn how to play, the most you’ll set yourself back by is 6 months. If it’s 15 years or more (like me) then you’ll probably have a bigger decision and more to lose by switching your game to a stick, and a lot further to go to get yourself back to where you were and start seeing improvements that you wouldn’t have had otherwise.
It really comes down to personal preference. I play on both pad and stick, but realistically speaking, i am just better on a pad from years and years of battling on consoles all the way back to the SNES, and i just can’t cut it at the same level on a stick, purely because i’ve gotten so used to a pad and pushed my technique as far as it can go on it that it’s like instinct for me to use one. I could get to the same place with a stick, but it would probably take me another 10-15 years, and i just don’t want to set my game back my that much, and by then there probably wouldn’t be anybody playing my fave games anyway…
If you feel that what you stand to gain by learning a stick would be worth whatever setback time it would take you to get your game back to where it was, and that there would still be people playing your fave game by the time you’ve done it, then go for it, and if you don’t, then don’t, but i’d hazard a guess that as you’re posting in the noobie section, you’ve probably not been playing too long, you probably don’t have too much to lose by comparison with a lot of more experienced players, and you would more than likely be doing your game a big favour in the long term by switching to a good quality stick if you’re serious about improving.
It really is down to personal preference though, so good luck with it!
