I don't that it's as much opinion that varies than it is actual experiences. Switch failures have been reported with both types of fluid, but of course that's no surprise - switches fail eventually even if fluid compatibility isn't at question. But the preponderance of reports seem to focus as DOT 5 and being cited more frequently with switches that failure before what people assume should be an acceptable lifespan. Sounds like you're looking for some fundamental scientific assessment - none that I'm aware of.
