There are many fine manufacturers on that list, 14 of which I have direct experience with to varying extents. I voted for HK. What can I say - German engineering. The workmanship, fit & finish, and (most importantly) the results when I squeeze the trigger are all unsurpassed IMO. I also know some gentlemen who have real-world experience with HK pistols in the sand, dust, and mud of SW Asia and they swear by them.
HK it is.
