We use banana plugs because they give a better connections and look more professional. When You get into large systems in custom cabinets, etc. it is much easy to push in a banana plug than have to screw/unscrew the terminals while you make adjustments. Also, I have had too many service calls because one strand straid from the rest and was touching the other terminal. Most of the time it doesn't even have to touch as long as the volume is low there is not enough juice to do an damage, but when you turn the volume up the receiver will shut down.

We use the crimp on ones. The screw terminal type are too big and bulky, and you might as well you the screw terminals on the receiver/speaker. We buy in bulk from a distributor. I will be willing to sell you some if you are interested.
