Best knot for joining two lines

The best knot I've encountered for joining two lines is the albright knot. I've used it with great success for joining leaders with mainline, backing and even braid-braid.

Any other joining knots people trust/recommend?

Reverse Albright

I was always an Albright kinda guy - I now use the Yucatan knot more often than any other.
