It all depends on the thickness...
from .001 up to say .030 the absolute best manual process is PAW (Plasma Arc Welding) then TIG(GTAW). Plasma will allow more control at these thicknesses and a finer weld. Tig can tend to be unstable at <5 Amps unless Micro-TIG or a similar process is used.
From about .020 up to 1/4 or 5/16 then PAW becomes a little tough to use and this is where TIG comes into its own. SS Mig can be used at the upper thickness if appearance is not critical.
from 5/16 and up MIG is the most economical and least time consuming at these thicknesses. Tig becomes a little hard because of the time it takes to fill these larger materials and the amount of interpass cooling times. Stick has been implemented at these thicknesses but I always prefer using a non-flux process when working with stainless.
There are also many other automated and CNC controlled welding processes that are can give even better results such as LASER, Electron Beam, Friction, Flash,plus automated TIG, MIG, and PAW.
Hope that helps.

If you have access to a wire feed welder,this would likely be the best for most applications. It requires a spool of stainless wire and a tank of special gas blend that contains three inert gasses. Without a wire feed welder, the other option is a standard stick welder. Not quite as easy to use but considered by some to be a stronger weld in some applications than a wire weld. I have never had a problem with the strength of wire welding and I have done a lot of it.

tig is first second is mig
