Well, for what it is worth I will state that I owned both the Golden and the Outlaw, but have never tried the Vaq. (I am considering it though). This fall I needed some cash and had to sell one and there was no debate... I sold the Outlaw. I like the Golden that much! I will never sell it. It is not very deep but it is a lot of fun and it's notching ability is quite unique. Of course, knowing that I could turn around and buy another Outlaw also helped, whereas the Golden is hard to find at a reasonable price. Happily, I got mine new just 3 years ago (some left over stock from a dealer), so mine has the lifetime warranty.
The Outlaw has a great discriminator on it, it separates well at the higher end of the conductive range of targets, whereas it seems that most of the other Tesoro's, including the Vaquero, separate better at the lower range of the conductive scale, but is only based on what I have read. Hoping to try either the Vaq or Tejon this spring, so we shall see.
