My newest sticks are all "universal" wired. I bring the common ground, buttons and directionals out to a Male DB-25. I then do a "padhack" to a female DB-25 for the various consoles (or PC) that I want to eventually connect to. Doing this, I've made "adapters" for XBox, XBox 360, Dreamcast and PC.
I've built various sticks, one using all Sanwa parts (JLF stick), one using a Korean stick and Happ Buttons, one using the MagStick Plus and Happ buttons, and eventually will build one for my Suzo Inductive, Euro Stick, and Sanwa JLW sticks. This way, instead of building 24 (or however many) separate sticks, with all the necessary "padhacks", I can simply build 6 base sticks utilizing the various components I want and then connect them to whatever platform I'm currently interested in playing.
The only stick not running my universal setup is the Happ/iL Pac Reunion stick that I linked to above. That one is "dedicated" for XBox use (mostly for Mame and FinalBurn).
I'm so indecisive about sticks and controls, so I need to keep my options open. I think everything I do in the future will be based around similar universal layouts. That way I don't regret any specific component or whatever, it's all swappable.
