I will echo what DocGKR said.
I exclusively carry 1911's and choose to because of the fact that I am left handed and can operate the 1911 with ease. I also like the conceivability of the single stack.
That being said it is a platform that requires you to be on top of it. The springs need to be changed more often then in modern designed pistols, a mismatch in tolerance will cause all sorts of heart ache, and one that is built wrong will just never work right without the help of a master smith. It does require you to pay attention to wear and maintenance much more than a modern tupperwear gun.
I would suggest if you still decide to buy one from Brown spend a little extra and have the common parts that break and wear fitted and tuned. (extractor, maybe extra bushing, recoil plug, etc.) If you do not want to do that a Springfield will allow you to get replacements with less "fitting" required on the semi-customs. I would stay away from the Schwarts too, just personal preference.
From your post you sound well read on the matter and will be able adapt to the nuances well. But if parts and smiths are hard to come by it might be something you take into your decision.
