I have thread milled thousands of parts mostly out of 316 st. st., Inconel and Hastaloy anywhere from 3/8" UN to 3/4" NPT thread depths yp to 4 diameters. I always start at the bottom of the hole, climb mill and I take two passes. the thread will not vary and the tools will not break. Depending on what manufactor I am milling with is the software that I use, just because it will give me the best tool for the application I am using at the time. They all will give you the software for free when you buy their tools.

I have also started at the bottom and climb milled with the same exotics for over 20 years. Works for me. I might add that I prefer solid carbide thread mills vs insert thread mills. (works much better)
