We use the screw type but the compression are better. The more metal that touches the wire the better the signal transfer. Actually soldering the wire to the connector would be the best solution. So why do we use screw connectors? Faster. And we are generally using banana plugs with distribution amps feeding in wall speakers. It makes servicing the systems easier and faster. In your case I doubt that time or money is a factor. Have you looked at the WBT connectors?
Crimping is the best imo, but only if you can get a good crimp. solder is good too, but only if you can solder properly. The wbt crimp on sleeves with their bananas are a pretty good compromise that is pretty easy to do properly with their tool, but the price!
Then again, if you look at the pricing for professional crimping tools, it comes out looking cheap.
