Ideally, none of us would ever go waterless. The primary benefit of washing with water is that you can blast dirt off of your paint without compressing dirt against the finish. You lose that with waterless obviously. With that said, waterless can be done properly with the right technique and tools so that swirling or marring is largely avoided.
The two CG products you linked to are great, I've tested them many times over the years and if you use them as advised, you won't cause any damage.
If you guys would like, I can make a video going into the process of using CG Waterless.
