Try out playing with a stick for a while. Indeed, you will lose quite a bit no matter your skill level- but give it some time. A month or three should be good.
I tried stick before... eventually I realized it just wasn't for me. Maybe it was the way I was sitting, or that a stock TE isn't built for my specific playstyle, but it never felt comfortable. There is actually an inherent slowness in sticks due to the physical distance from neutral to throw (which is blazing lightning on pad). Some people will say that you are not supposed to "ride to the gate", instead gently brushing the switches- but, I just can't play that way. I need hard feedback.
Switching to a tighter Seimitsu did result in a speed increase, but it still never felt easy to use.
Anyway, you may be different. It's all about being comfortable; you may have to just go hunting for another pad, or just stick it out with stick (no pun intended).
Stick does have big advantages when it comes to button layout/quality, dual mods (why is there not a plug-and-play PS360 pad on the market?), and the ability to naturally sit down and play in Japanese arcades (if you find yourself there).
