It actually depends on what you get used to,
Some people use arcade sticks and they're very much used to it, and don't know how to use a dpad properly.
While others can probably beat arcade players with just a dpad, regardless if it was a PS4 or Xbox or a 3rd party.
I don't think I will be able to get used for an arcade, I've been PC player and old console player (nintendo and Sega, and I played the UMK3 on Sega flawlessly and won several tournaments back a day. as well as MK3 on PC.
For me Hori Fighting commander 4 resemble to the Sega dpad (which had 6 buttons) and it was the perfect match for MK back then.
I guess I could also do very well with MKX using a keyboard.
so based on some reviews to see what people prefer, and mostly is what you're able to get used to, and probably get the Titan one converter and connect your keyboard.
