First, all firearms to be carried would be tested first, regardless of what brand or model they are. There is nothing I would trust to carry without shooting first. If I were buying my first handgun, it may get carried before I can verify its working, but only because there is no other proven option available.
As to which gun I would trust above, well all of them and none of them. They all have the capability to be dependable, accurate, long lasting firearms. They all have the capability to be out of spec, broken, or improperly assembled.
To answer your question more directly, the CZ would be top on my list as it has a great service record (more so outside the US) and is a great price for what you get. The HK is certainly a good pistol, just expensive (to me) so it would be a good option if the price didn't turn you off. The FN is a firearm I'd trust as well but for some reason doesn't raise much interest in myself.
The 1911/2011 would be a big maybe. Some are well built, some aren't. Some follow the original specs closely (at least in regards to moving parts) and some take liberties changing spec how they see fit. The original spec was very reliable with ball ammo. They also started as fairly tight guns. When seeing one of those run well it shows that a reliable 1911 is capable to be made and the specs to do so are widely known. Then we get into small changes to appeal to more shooters as well as less QC and larger tolerance specs and who knows what you are getting.
For a fighting 1911, I'd have to buy one from a company that is known for making quality defensive 1911's to feel good and then it would need to see plenty of range time to verify it is reliable. The 2011 tends to be a top tier build at a top tier price. Some aren't (RIA and PARA) but most use top quality parts that are hand fit one gun at a time to customer spec. If you are having that done by a competent smith (I'd argue most who have a reputation for building a 2011 would qualify) I'd feel comfortable with the gun but again want to verify it's function first at the range.
Another I would throw in and seriously consider is the M&P with thumb safety. I really like the M&P. It fits me well and I shoot it well. The factory sear gets swapped for an APEX version, though pull weight can be set to fit the use well. If you don't want to swap things it may or may not be the best fit but it's still a way to get a lighter weight double stack with a thumb safety.
If the question is meant that you go to the gun store, see all of them in the case, buy one, and have to use it for self defense that night, I'd probably want the HK or M&P, followed closely by the CZ and FN, and then lastly an untested but quality built 1911/2011.
