It’s pretty much what everyone says…use whatever is more comfortable for you. I’ll chime in here b/c this thread reminded me of when I first got SF4.
I started off with an X-Arcade (one of the better quality revisions) + PS2/PS3 adapter (with no lag!) before I got my hands on one of the 2nd batch Madcatz TE sticks. I mained Gief from the start and pretty much grew up with the American-style Happ parts from the arcades - but I’ve also played with some SNK (square gate) joysticks when my friend had a Neo Geo. Since I got the TE, I haven’t looked back. So here’s the breakdown of just my experience.
Generally speaking (unless there’s tweaking), the American sticks and buttons are more springy and require more force to use. The stick itself is very tight and makes the Sanwa stick feel VERY loose by comparison. The American buttons require more force to press than the Sanwa and not as easy to “glide” over since they are concave. The gate itself, coming from no/circle to square, I immediately noticed that there’s less movement (almost feels limited) allotted when spinning the stick around. Also, with the bat top, you’ll notice that you have to hold it a bit higher than the ball top. With that, it means you have to make bigger circles for moves to come out.
When I switched over, fireballs and uppercuts became a flick of the wrist. Less movement made me less worried about my execution. With Gief in particular, I didn’t have to make a huge motion on the TE (a flick of the wrist) to get SPDs to come out. I’ve always been able to get standing SPDs easily on both sticks, but on the TE it felt a lot cleaner and I felt more confident just walking up to someone and pulling it, vs before when I felt I had to “prep” my wrist for the motion. As for the buttons, I didn’t miss the “click” after a bit. Yeah, it’s nice to “know” that you pressed something, but when linking or even plinking, I noticed I had to rely on making sure those buttons actually clicked before I could press something again (some people prefer that, not me though). Also, with the buttons is the ergonomic setup. On the TE, I can just rest my hand on the stick and my fingers are comfortable hitting the punches and kicks easily without shifting much/any. This helped me in that I didn’t have to move much to get the buttons needed - for as we all know or find out quickly, every split second counts.
Another thing that may have been covered in other stick comparo threads is hand/wrist fatigue. This is one of the reasons why I will never go back to the X-A/Happ parts. When SF4 first came out, I hopped right in to start learning it. Probably the same for many other people, I spent a number of hours straight on the game throughout the weekends following release. After a long session of spinning the “rough” X-A stick around and pressing the harder buttons, my wrists and fingers got really stiff. So much to the point I had a weird thumb/wrist injury thing going for a bit. When I broke it down, it was probably because of the non-ergonomic setup of the X-Arcade. Combine the stiff joystick and buttons, the non-centered stick/button placement (seriously, the X-A is just weird), and the non ergonomic button progression of a straight line, it will really do a number on you after a bit, especially if you’re tossing up 360/720 movements and mashing those 3 punch/kick buttons.
If you have any other questions/thoughts, let me know!
