The AC1900 and 1300 are both much faster. N300 =300 theoretical Mbps. Ac1900 = 1900 theoretical Mbps throughput. With your comments about the limitations you face, the Jetpack is 450 Mbps so, your theoretical cap is 450. There Is no need to spend the extra money and you would never see those theoretical speeds anyway even if you had a Fiber connection. Even with Fiber, there is some deterioration of advertised residential speed.
Of course, if your like me, you want the fastest and shiniest. For instance, even though I can't drive 220mph on my communities roads, I still want a Z06 Corvette. :)
