I'm going to go ahead and say that 100% of my 31 mile round trip commute has NO bike lanes, which to me is an UP. No dangerous edge facilities to deal with, or the harassment that comes with not using such edge facilities when they exist.
Also I'm the ONLY person I ever see on a bike during that whole commute. I think that's a good thing, also, as I don't have to deal with unsafe practices by other cyclists, and the associated harassment from motorists who think I should do what the other cyclists do (ride in the gutter), or who may think I do what other scofflaws may do (ride against traffic, blow red lights etc.).
