We all have our favorites, and to be sure that is probably determined mostly by how we manage as we form the knot. The best knot can and will fail if fashioned up incorrectly. I suggest trying several of the ones mentioned, and maybe a few others, and see which suit your abilities. I mean all of our knots can and will hold fine, if formed correctly, so it really comes down to personal preference and skill set.

Knots are designed for specific purposes, and while one knot might be great for this purpose, trying to get it to work in another may leave it weakened. Read a little about each to determine usefulness. Deep sea knots differ from fly fishing knots for example.

They tell me spitting on the material keeps it from “burning”. I do not seem to suffer from this phenom, but do spit occasionally. It is when the knot has coils and needs to slide that I get spitty. Usually though I get by using my burnt up lines. LOL. Now spitting can and will get a knot to cinch down tighter. Of that there can be no doubt. So spit if it gives you something of value, such as slippery for tightening.

Also materials differ and certainly knot differently. Flouro differs from mono in how it accepts knottings. Try to read some about this and then relate it to the materials you use.

My offering is the Davy Knot. It however is very picky about how it is formed and is easily mistied. This leads to failures obviously. Some throw an extra pass on it and that helps, especially if the original was slightly misformed. LOL. I use it because fly fishermen have been using really light weight mono materials for decades and know which knots tend to fail. They like the Davy, which is actually called something else somewhere else on the planet. I like it because it is quick, simple and compact. It is my choice for fastening to swivels and clips and such.

I would also mention that many fly fishermen use the Cinch Knot, for all the reasons mentioned.
