New font looks a lot more clean and professional. Also quite a heavy keyboard weighing slightly over three pounds giving it a premium feel. It doesn't attract fingerprints but note it does attract dust. New metal finish looks and feels a lot more premium than the old one found on the original BlackWidow Chroma.
The Tournament X variant of this keyboard has Cherry stabilizers which is one of the main reasons I opted for the full sized version instead. They feel a lot more solid anywhere you press the keys. Costar stabilizers are used on this keyboard which I and many other people greatly prefer over the Cherry stabilizers. With the new Razer Green switch, they've bumped up the warranty from one year to two years. Razer has brought back traditional MX Blues for those that prefer them, but only on the BlackWidow Ultimate. Supposedly these are now rated to last 80 million instead of 60 million but only time will tell if that's true. These new switches sound better and feel a lot more crisp than the 2014 Razer Green switch.
Pros: -Razer has switched manufacturer of their switches from Kailh to Greetech and with that, there's been a vast improvement to switch quality.
