I've been using https://www.eff.org/https-everywhere https://www.eff.org/https-everywhere since 2011 (Firefox 3.6 back then) and only rarely see sites that serve a default page or stall with https. That's anecdata, but to get good data one would have to try to fetch & compare results from both protocols for many websites - perhaps Google or the Internet Archive has done this? The biggest annoyance for me in using https preferentially is that I often end up with multiple bookmarks for the "same" page, which differ only in their protocol - it would be nice if there were an auto-magic way to upgrade the old http bookmark to the https protocol.
