i like the Nikons and have a couple of those. 6-18's power with side adjust.
I would say those or Vortex.
I would also suggest the bullet drop type reticle. I find that those type of reticles, when practiced with, will allow you to get on target, and shoot a lot faster than dialing and twisting knobs.
For some reason coyotes just don't seem to hang out that long, to take your time like you can with Elk.
If i have a a coyote at 300yrds, i know that i just twist the zoom to 10, use the first circle down and aim for center mass. Maybe left edge or right edge depending on the wind.
