I have a strong preference for TIG but I'm biased.  I learned to weld with TIG when I was 16 and I was a coded welder on stainless.  I've also done a lot of copper and aluminium.  Welding with TIG is the easiest thing in the world and you can get the nicest looking finish.  You can also do some dissimilar metals with some success.

The reason you need AC to weld stainless is the AC scours off the oxide which forms very quickly at welding temperatures.

And yes, the current does go to zero twice very cycle when welding with AC, it just happens so quickly that you do not lose the arc.
