How bad is stainless steel fatigue?
(OP)
Is there a distinct (and high) fatigue limit for stainless steel?
In other words Is there a fatigue limit force below which even millions of cycles wouldn't cause failure. Pretty much like Steel compared to Aluminum
Is there a big difference between Austenitic, Ferritic alloys?

RE: How bad is stainless steel fatigue?
Like steels, if you stay below a critical stress level you will have infinite fatigue life.
Alloy 21-6-9 (in the cold worked state) is used in aircraft hydraulic systems. At test stress levels of 30% of UTS the fatigue life exceeds 400,000 cycles. In service at 20% of UTS it will last forever.
13-8PH is also commonly used in high stress fatigue applications. There is a lot of data on this alloy.
Ferritic alloys will have very low fatigue limits because they have low strength.

In regards to your specific question about a "distinct (and high) fatigue limit for stainless steel", you'll need to define what "distinct" and "high fatigue limit" implies.
