I have turbo 1&4" on the fly adjustment types on my bikes and don't think I would like to be without an adjustable seatpost now. I use it many times on a ride.
I am tall, and these type of posts are even more important for tallies. I prefer the Gravity Dropper brand, but there are a bunch of others out there. This will change your life in a big and good way. Instantly, your COG can go 4 inches lower, so if I am not climbing, or needing a lot of power on the flats, that seat stays down.
I sometimes let my more normal (and shorter) friends try my bikes. Many times I just put the saddle down and lo and behold it is at the proper height for them. This means the handling they experience all the time is something I need to put my saddle 4 inches down to experience. Folks with lower saddles already may not get the dropper thing, but I guarantee it will change your riding experience for the better
