I don't think they are subjective at all. Tor is inherently slow based on how it works. It has gotten faster since inception but even in last year or two it is a multiple slower. Until that is non-existent adoption will be challenging at best.
What I’m saying is that Tor used to be, many years ago, annoyingly slow, sometimes even excruciatingly so. But today I don’t even notice that I’m using Tor. It might be “a multiple” slower, but I don’t notice it, is my point.
