The AMEX Platinum card offered this as a reimbursement upon enrollment, so look into your CC because you never know what perks they might have. Husband and I both have Global Entry which includes Pre-Check and its been a great perk we'll never let expire. If anything, there's peace of mind knowing you most likely won't have a long wait, and yeah, not taking off shoes and belts and unloading computers, etc, IS nice. One less thing to deal with. We've used Pre-Check several times and beat the lines on a regular basis (we fly out of DFW/DAL often). Regarding Global Entry, we used this after our trip to Mexico in 2021 and we were one of 5 people in DFW using it, so we had ZERO wait through customs, whereas the normal line was backed way the heck up.
What I will tell you about Global Entry is that they are back logged by 9 - 18 months. I submitted my 15 year old's application in March and haven't received so much as a conditional approval, which is nuts because he's a kid and there's really no "record" to look through, lol. So if you don't have time to wait, just get Pre Check and consider Global Entry if you find you're going to be doing a lot of international travel.
