I have Global Entry (you would too if you've ever seen the ghastly passport-control queues at Dulles international arrivals at mid-afternoon) which also includes TSA Pre-Check. One thing that has to be borne in mind is that TSA Pre-Check changes constantly, often several times during the course of a day - for example, spring of last year I took two trips to Europe; on the first of these trips they did little more than wave me through, but on the second trip they gave me a quite thorough examination. And coming back from Paris in April 2018 I had to come back via JFK since my original flight back to Dulles was cancelled due to a strike - and at the Delta terminal where I would make my connection they shut down TSA Pre-Check altogether and everyone except Sky Priority passengers had to go through the regular security queue. (I have read of this happening at the international terminals of other airports, notably Chicago O'Hare.) On the whole, though, it is a quicker security procedure.
A few airports in Europe offer similar services: London Heathrow has 'Fast Track' security available to anyone flying business or first class (no membership or other extra charges). I have gone through this twice and in my opinion it's overrated - in both cases I got the full-scale inspection that took just as long as regular security; the only advantage was that the original queue wasn't as long.
