Sir, please do not be misled. You do NOT have spend $1,500 and thousands more to have a good, workable, useful 1911.
The good old 1911-A1 was fielded and carried for years by the US military, from WWII up and including use in Desert Storm.
You can buy nice replicas from Springfield that will give you a reliable functioning 1911.
He asked what was the top three 1911's. Dan Wesson is the best production 1911, Brown and Wilson are the best semi-custom 1911's. The guns you refer to, are generally serviceable, but will generally need some tweaking, at least, to run reliably. The above three I mentioned will run right out of the box. Remember, with the exception of Kimber, you get what you pay for in 1911's.
