Chuck, I work for a National Telecom company here in Canada and we crimp everything used on DS-3 (BNC) and above. For the center pin you need a 12 point circular crimper and for the sleeve you need a good quality hex crimper such as Tyco etc. These two items can run you several hundred dollars each. The SMB crimper that we use costs around $1100.00
I've probably done a few thousand of them and never had a failure. So the trick is to have good tools and know the proper way of installing the connector. Seems to me that someone once mentioned that you must use crimp connectors on aircraft...??? ....not sure if that is true....

Whether there is a practical (measurable) difference would depend on how well the crimp was done, vs solder. From an Amphenol paper: "Cable Attachment: Mechanical stability of the cable/connector junction is of utmost importance. Small movements caused by flexing can be translated into significant PIM. Center conductors should be soldered, not crimped."
