I am a big fan of the European style connectors. They are reliable and do not require the wire to be bent around a screw. They can be trimmed to length and each conductor is completely isolated. I use this style of terminal strip for all my connections where a terminal would be appropriate. Otherwise, also being an air force guy, I open, wrap, and solder. I may re-examine this since while I share the same misgivings about suitcase connectors they seem to be working reliably for a lot of people.
The "Eurostyle" fix a lot of issues, but the problem is with the screws backing out under vibration. The cheap ones available at places like radio shack have no sprung metal to keep the screw from backing out. I've seen wires fall out of a euro-style strip after transporting it a long way.
Some of the newer ones you can get with an internal spring. Really it's just a slightly bent piece of metal where the screw goes in that keeps pressure on the screw and prevents vibration from backing it out. These would probably be ok.
How do we get people to know the difference?
