Also consider that for a stick. I'm not a big fan of posting in threads if you're wondering why I left a message here. It was my previous stick before I lost it and I loved it. I bought a SFIV TE from a friend at a reduced price since he quit fighting games. I also highly recommend them as well. Also, if you're wondering, the original and round2 fight sticks have no difference -- quality-wise.
Edit:
Oops, hadn't realized you asked for an Xbox stick. By all means, go for the TE. You can mod it for both consoles easier on the Xbox one as well.
