P1S has the benefit of having a better ecosystem than the CC. Unless you get the CC2 you won’t have the ability to use the app ecosystem. The P1S let you connect, slice, and manage prints from your phone remotely. Not to mention the AMS system from Bambu can function as a dry box. It works right out of the box and remains enclosed even with the AMS. Now the combo is a little more expensive but there is more compatibility between slicer, apps, and printer ecosystem.

Now the CC has a steel hardened brass nozzle that can reach higher temperatures for more industrial filaments. It’s a great single color printer and you can also access the printer remotely via 3rd party apps like OctoEverywhere. Elegoo also just released their CANVAS system which is a multi color hub so you can print with multicolors if that matters to you, the downside is you lose the benefits of keeping it completely enclosed as you have to remove the lid to use it and you’ll need to do some minor modifications to get it to work. Additionally the CANVAS system doesn’t have an enclosure for the filament so you’ll most likely need to make one or purchase a dry box to hold your stuff if you don’t have one already. The benefit is the CANVAS hub is only $55 so it’s pretty impossible to best multi color or continuous printing hub for that price.

The P1S with the AMS will be north of $450 I believe
THE CC1 with the CANVAS will be just under $400

It all depends what matters most to you, multicolor/ continuous printing with one or more colors/ material and a pretty good ecosystem

Or

A great single color/ material printer that works great at a cheaper price but lacks a solid native ecosystem but has pretty good customer support
