Pros of the UH-1 Gen II include long battery life, (8) NV settings, a large window, and a warranty that will cover anything that might ever happen to the optic, regardless of circumstance.
Yes, with standard height irons, the UH-1 Gen II allows for a lower 1/3 co-witness.

That decision is entirely up to you in regards to what you want. The Holosun is a bit smaller in overall dimensions, but you lose the "Holographic" as the Holosun is a standard red dot while the Vortex is a holographic red dot.

No, this optic is a standard holographic red dot and does not have a "night vision mode" that will allow you to see at night. What this does have is night vision illumination settings. This means that the red dot has brightness settings that are low enough in brightness to be used with a separate night vision device like a PVS-14.
It should fit since it mounts only on 1913 and picatinny rail.
Vortex proudly manufactures all of their "AMG" products in the United States.
We recommend reaching out to manufacturer about that question as Vortex unfortunately does not list the window size of the UH-1. Here is their contact information:
