I have that pad (or at least this one, assuming it is the same pad), and I quite like it.
If I had any issues with the FC4, it would be that there is no touchpad functionality, and that the d-pad is maybe very slightly too tall for my personal taste. It's a very good d-pad mind you, but I feel like you'll develop callous a little faster since the gaps between the cardinals are pretty pronounced at that height with the rigid plastic (though probably quite durable, feels like it might be PBT or POM rather than ABS plastic). They've rounded all the edges on it well to combat this, but each direction also angles upward slightly as it comes away from the center rather than being flat, so you still feel it on quick sweeping motions. Good I think for input accuracy though, I think.
The shape and layout is near perfect though, maybe the best ever in that regard in the context of fighting games. The triggers feel slightly less solid than the face buttons because they're flattened out, wide buttons (which is ideal for digital input) but don't necessarily have great stabilizer design. It's never once caused me to drop an input or anything like that, they just don't feel quite as nice as the face buttons.
I'm very glad the FightPad is taking a lot of cues from the FC4. The concept of the d-pad on the FightPad is more up my alley, but hard to say how well it works in practice. The layout and shape though look very similar which is a great thing (especially implementing the trigger swap switch, which is very useful). What I'm most curious about other than the d-pad is the build quality. Given that they're asking a fair bit more than the FC4 I think they need to prove the merit of that in the construction and materials; I don't think the additions of the touchpad and analog stick quite cover the difference.
