These are great for terrestrial, but horrible for the sky.
If you set the tension screw for azimuth to make the scope smooth to move, when you tip the scope back to view near zenith, it will cascade on you. If you set the nut tight enough to keep it from cascading, it will be so stiff that it is hard to move when re-pointing.
Horrible for astronomy. OK for terrestrial use.
Otherwise, I realize the question is hypothetical, but none of these mounts are all that great.
For astronomy though, the AZ3 is simply inferior to the small GEMs.
And if you don't need tracking and the scope is light, I think the AZ4 might be OK.
The GEMs you mention usually don't come with dovetails and these days, that is the only way I would mount a telescope.
Maybe they have some with dovetail saddles now though, but for me, I would not own one if it did not allow for quick mounting/unmounting.
So, AZ4 if you made me pick from these and I did not care about tracking (though I just can't hardly use a telescope if it does not track)
Since your question seems to accept non-tracking is equal though, I would think the AZ4 would be the best of these.

have you tried the classifieds here on CN, you can find better used mounts than that eq3, just like the other poster mentioned
