Although I didn't get this for SFxT, I did however use this to play SSFIV. And I must say after so much mixed ideas about this controller I decided to pick up the PS3 version of this controller. Although I did care for the art a bit, in the end I sucked my pride and bought this.
This pad is pretty light and feels like a cheap knock-off SEGA Genesis 6 controller, HOWEVER, this is not case quality wise. The front face buttons are nice and sturdy like all buttons should be and they are placed such that if you use all but one thumb or two or three fingers, it doesn't really matter it still feels very comfortable to play with. Especially with my occasional Carpal Tunnel Syndrome pains I get, this really compensates for it. The shoulder buttons I'm quite surprised about because generally with shoulder buttons I've always loved them from the SNES to the PS3 pad (haven't tried PS4 or XBONE yet) and those I really liked. This one on the other hand had a weird press; to get a good input you had to press the button more towards the middle of the controller (so pressing the button on the side more towards the wire cord). This did let me down when I attempted really quick Ashura with Akuma, or a Kara Demon Armageddon. They're very responsive though but the class press from the opposite side of the button wouldn't have been to hard to put in. Again this is where my carpal syndrome pains would come in, but since I barely use the buttons as of yet it's bearable. This pad really fits my hand, even though my hands are small-medium sized I still can get a good grip on everything without getting those damn pains, so that'a huge plus.
The D-pad which is the most important aspect of the controller, I'd say this is just slightly under the Original SEGA Genesis 6 button controller D-pad, it's slightly flimsy but motions like QCF and DP are very easily executed. And even motions like Double HCF is pretty consistent with me. There are no textured surface so your thumb can slide around making these motions easier than anticipated. I've had this for a few days and with heavy usage, with this most people who used this controller say this D-pad no longer responds; but I'm here to tell you that this version of the pad has not had any errors whatsoever. Diagonal motions like forward jump and backjumps, forward crouch, or back crouch are really easy to do and don't take a hard press to activate. So you could say it's a hybrid between a Analogue nub and an arcade stick (you could say so).
Miscellaneous things, like the cord length is really big. And with my previous arcade stick I owned, this pad beat the cord length was about > 10ft. The home, start, select and turbo buttons are out of reach when you play those intense matches you don't press any of those buttons resulting in a DQ if you're in a tournament. Art quality wise, the stick can be chipped off but with usage scratches or the occasional rage controller throw will pretty much show a little bit of chipping but that's not an issue with me but could be for other people. There's the new addition of the switches on the back of the controller, for the Directional pad, Left stick and Right stick. A MadCatz innovation where it's really appreciated and the switch is very sturdy so you wont be switching between the sticks and pad if you do happen to touch the switch.
I bought this for about £12 incl. P+P; is this worth my investment? Yes it is.
Is this an alternate for an arcade stick? Yes it is.
Is this better than the PS3 or XB pad? Very much so and you won't be disappointed.
Can this up my skills in any fighting game? With dedication and some time, yes it will.
Does this work for any other games? Of course, I played some spaceship shooters.
Should I give this a go before getting a Stick? Yes by all means, I think if you use it before making the huge transition to the stick it'll definitely give you some edge.
Out of 10 what would you give this? I would say about 8/10, and for fighting games although I'm a die-hard stick player, I'd say this practically gave me my old pad skills back in just about 15 minutes of using this.
