What type of router is best for a college dorm?

So in August I will be moving into a single college dorm room with pretty bad wifi. So, I am thinking about getting a router for my room. I will need to run a lenovo gaming laptop, an iphone, ipad, and a xbox one. Since its just for my room compactability is very important but range isn't a top priority (throughput over range, although more range doesn't hurt). It should to be dual band and preferably 802.11ac, also no antennas (that's not a requirement just a personal preference). I have a Netgear N600 Premium that my parents bought in 2011 that they can give me (they only used it for like 2 months), but i don't know if that router is fast enough given the pace at which technology has advanced.

Some ones ive looked into: Netgear R6300, Asus RT-AC87u, Asus RT-AC68u, and Trednet AC1900 Dual Band.
