Your question is vague. The only answer is "any".
#1 in 1911's? In 10mm many of them aren't 100%, but many 1911's run 100% in .45ACP.
My Para converted 16-40 (Canadian ) 10 mm runs 100% ;D
I don't understand the question either.
Ftfeed ? Fte? Stove pipes? I have a colt delta elite and when I clean and oil it take takes about 2 clips to start running smooth again . With mine it does anyways . I think the oil gets on the brass and makes them slippery and the ejector can't grab the case . I hope this is what you were wanting.
Never had a problem with my Para 1911 or my Delta Elite 10mm as long as you don't try to use Buffalo Bore's ammo in the DE (as their product claims is ok).

Which is the better 1911 platform. The 45 or 10mm.
They are one and the same. The 10mm may wear out sooner, theoretically.
The 1911 is a platform. Just like the Glock is a platform.
However, the large frame Glock was originally designed for the 10mm then modified to function with the 45 acp. A fairly easy feat going from the high pressure 10 to the 45 and their was only one company and one design team working on it.
The 1911 was originally designed to function with the 45 acp, (in 1910) and has been fairly well perfected. The biggest issues are when companies use cheaper parts to cut cost.
When the 10mm hit the seen in the 1980's, the basic 1911 platform had to be modified to work with almost triple the chamber pressures and almost double the slide velocity. By then, several companies were making a 1911 and different design teams went in different directions to tackle the problem. On the extremes, Colt went the cheapest route by just adding more recoil spring while Springfield Armory completely redesigned the locking system using Peter Sthal's linkless system along with barrel porting and extra slide mass. Since then, several companies have also addressed the 1911/10mm issue with quite a bit of success.
To answer what I think is your question, it depends. If we're talking full size 1911s or the newer 6" models, both calibers work quite well. It's when you go down in size that it becomes relevant. When you reduce slide mass below say, a commander size, it's easier to get a 45 to function with all the ammo that's available.
Hope this helps.

Thats what I was looking for, I think above government side the 10mm is better and at the commander size and below the 45 is better.
I thought the question was more about which company sells the most 10mm 1911s. Which is an interesting I don't know the answer to.
I agree with everything fltbed said.
If you tell me there are zombies outside and you can give me a 1911 in 10mm or 45 ACP, I will take the 45 ACP.
If you tell me I have to own a 1911 and can pick the caliber, and it has to be my only gun, I should pick 45 ACP, but would pick 10mm.
If I get to have other guns to, then I would (and did) pick 10mm, but I have other guns that I would use if the Zombies came (also 10mm, but different platform).
