Actually, wrapping the wire around it eliminates connections furthermore and is probably still the best way to go.
Are we talking about 5 way posts or the smaller and older screw terminals? I agree on screw terminals. The only downside is that the screw must be completely removed in order to remove the cable.

With the 5 way posts, I kind of agree. The better spade lugs have the ends tipped up so that they won't slide out unless the terminal is fully unscrewed. If you use bare wire, you end up with fraying problems. A better solution is to tin the end and then stick it through the hole in the post, basically creating a pin connector. However IMHO the best overall solution is to use the banana plug, especially the ganged and keyed one, like this one:
