I like to plan and feel less anxiety when I plan and know what to expect...
When we went, the Counter Service meals were so much more stressful. I knew ahead of time that all the ADRs I chose would have something for everyone, but picking Counter Service was almost too many options that 4 adults had to agree on or split up (and we weren't really splitting up on this trip). Then someone had to get the orders and someone had to get the table.
I just don't see it as that cost saving...unless you really try to max out everything (buy a dole whip float with every snack and eat dessert with everything

). I guess if it's "free" and you don't have another discount it is good, but if I was going to just eat CS, I would pay OOP
ETA: But I guess that is why Disney has so many options. Oh, and so they can give free QSDP (at value and moderate) and call it free dining
