If you live in the US, based on current Amazon pricing, your best choice by far from within that list would be the Audio Technicas. They are not only cheaper than the others on the list, but also both superior comfort and audio quality. They may be the only ones on your list that aren't marketed for gamers, but they actually win there too, offering the largest soundstage of the bunch.
Keep in mind the AD-700x/900x is open, while the A-700x/900x (no D) is closed. They each have their strengths and weaknesses, so you will have to choose based on personal preference / usage. They are also the only ones that do NOT come with a built in mic. This is a good thing, since built in mics are always incredibly overpriced and just add another point of failure that will shorten the lifespan of your headphone investment, but it does mean you will have to pick up a separate mic if you want to be able to use voice communications, youtube recordings, etc (unless of course you already have one).
