The previous edge (at least the latter versions) weren't that bad. I had about the same amount of issues with safari and the edgeHTML edge, but the big difference for me was that at least I could test edge legally on a non-windows machine while I cannot for safari. I also ran into some issues of corporate policies holding back updates, which seems like a "unique" "feature" of windows.

Not being able to legally, without paying, test safari compatibility is crazy to me.
