Since the question was VALUE, not how many dollars did you save I still come down on the side of FSD. You may not think it's replacing your chauffeur, but it IS still a second set of eyes on your driving. I feel a LOT more confident having the car keep the frick away from sus cars and windblown trucks as I scoot down the highway. Sure the safety modes of the car are fine, but I would MUCH prefer that it come slowly to a stop at a sign that I didn't notice than have it scream at me to frickin' stop already.
There is value in that.
Sure you can save some dollars on charging for free, but those cars that have that feature also charge really slow (mostly). So you are DOOMING yourself to slow charging even when you are in a hurry and just wanna make it to the basketball game in Colorado on time. If you have the time, hit up one of those slow CCS chargers that are free or cheaper than Supercharging, but when you need it you have 250kW speed to get to your destination in a hurry.
