Below is my Tisas GI edition .45 automatic along with WW2-based pistol belt gear. Below that is my Beretta M9 with a similar setup based on Desert Storm or early GWOT.

I love shooting them both and have a hard time picking which would be the one I'd want to carry in combat.
For me, the M1911A1 is a hard hitting classic and harkens back. But the M9 is a smooth shooter with benefits in capacity and (for me) shootability. It's a very tough choice!
What are your thoughts on the matter? Which one do you think was the better military sidearm?

I can answer your question in two ways.
The best mechanical design: "The 1911"
The safer design to handle and use: The M 92
The best caliber: "The 9mm" and read below why.
In 1945, 34 years after adopting the 1911 the U.S. Military actually tested the .45 acp v/s the 9x19 and what they found shocked them out of their shoes.
The 9x19 penetrated a steel military helmet at an astonishing 125 yards and might have done so even further away but no one succeeded in hitting it beyond 125 yards.
The .45 acp bounced off the steel helmet at a scant 35 yards shocking everyone.
Considering the fact that the 9x19:
Recoils less resulting in faster recoil recovery time. You can get off 3 shots to one .45 acp shot.
Less recoil results in more accurate shooting.
Holds twice as much ammo.
A man can carry more ammo.
Has a flatter trajectory making longer range hits easier.
Has superior penetration.
Costs less to manufacture.
A pistol with a decocker is a safer gun to handle.
All this makes the 9x19 the superior military round and just about every nation adopted it and roundly rejected the 1911 .45 acp. Now you know why they did.
So should the military have just rechambered the 1911 to 9mm?
No, as it was a big heavy gun and a pistol in 9mm designed from the ground up can be made smaller, and lighter and have less grip circumference so it fits a wide variety of hands. This the Beretta 92 did not do as it was a big gun like the 1911. A Plasticky pistol may turn your stomach but "without" removable grips the grip circumference is smaller and the 9mm cartridge is shorter in length which means it has a smaller grip circumference as well and the plasticky gun is lighter in weight. And the overall length of a new plasticky pistol can be made less compared to the existing and ponderous 92 and 1911 pistols. And as mentioned a pistol with a decocker, and a chamber loaded indicator is safer to handle and use (which the M 92 did have).
