One thing to consider is that sometimes a CCS charging station is in a somewhat better location in the same town as an SC. For example, in Cranberry, PA (just off the Turnpike) the Tesla SC is behind a Residence Inn, which means you have to go inside the hotel to use the bathroom, and there are no snacks or other food. The EA station (about a half mile away) is located at a Sheetz, with bathrooms and food galore. I trek that way frequently, which is one reason I picked up the Korean CCS adapter (which works perfectly).
Also, there are a bunch of slower charging (50 and 62.5kW) CCS locations scattered about in obscure places like Tiffin, Ohio. The CCS adapter comes in handy when you are doing the kind of lazy, back roads travel I like to do from time to time.
