The Tor Project itself has found that users often don't verify GPG
signatures on binaries (I think Mike Perry quoted some statistics about
how often the Tor Browser binary had been downloaded in comparison to
the .asc signature file -- it was orders of magnitude less often).  That
suggests to me that HTTPS should be used for software distribution
authenticity even when there's a signature available; the importance of
this only diminishes if the signature will be verified automatically
before installation (like in some package managers).  That's usually
not the case for first-time installations of software downloaded from the
web.

(I don't think the Tor Project has studied _why_ the users didn't verify
the signatures -- there are tons of possible reasons.  But it's clear
that most didn't, because the .asc file is so rarely downloaded.)
