Here's why I finally decided to break down and join Clear:
(1) From what I can see, Clear lines at SFO International Terminal (both A & G sides) completely bypass the initial (useless) ID screeners, the longer lines for the TSA ID checkers (which can be 15m even for C/F class) and the lengthy MMW lines. So Clear is guaranteed to save me 5-30 minutes at the beginnning of every international flight, depending on TOD.
(2) Precheck is hit-or-miss. Clear is guaranteed every time I visit my home airport (SFO) assuming my flight departs within the rather long window of operations.
(3) In one case (not sure if it was T3 or International) I saw the Clear line go straight to a separate WTMD line which completely bypassed the horrid MMWs - which is fantastic as Boraxo doesn't do MMW.
(4) Family add-on membership only $50 - that's probably a better deal than lounge membership in terms of convenience when traveling with small children.
Now if only we can get Clear at IAD and maybe ORD ...
