I guess that depends on your priorities. It has a competitive resolution and frame rate, is a bit heavy, has fantastic controllers, and has Linux compatibility. It’s also expensive and is best to pair with high end hardware.
So if you’re looking for Linux support (like me), it’s pretty much your only option, unless you’re willing to buy used or accept a lot of compromises. If you’re looking for cheap, lightweight, or compatible with lower end hardware, it’s not going to score well.
But on the whole, outside of pricing, it does a good job in almost every category. If money is no object, the Index is one of the best.
