The standard PS4 DualShock controller is very good, but if you're a dedicated fighting game player you may have found it wanting. Enter the Razer Raion.
Razer's first competitor in the niche fightpad market comes out swinging and achieves a decisive victory, although it's hard to say whether you'll want to use the Razer Raion for anything else.
The price of that though is insane. No way in hell it's worth that much and there are more than good enough alternatives for less than half that price.
