With 1000 posts now, wondering if there is anyone who wants to summarize as to whether it is "worth it" at specific airports?

For example at SFO I rarely find long lines, but others report the experience is quite different at IAD (apparently hasn't improved in many years). Of course it depends on how often you travel - saving 5 minutes in line might be worth $100 to somebody who transits once a month v. twice a year.
