I've tried it all. The TLDR is that bare wire would be 100% better were it not for the fact that a larger gauge wire than will play well with a binding post sounds better than a gauge of wire that'll easily wrap to a binding post.
The trade off of the inferior spade for the superior large gauge wire was the better choice (IMS).
