The Paris Museum Pass is much more reasonable but does not ibmnclude as many attractions.
Have you made a list of what you want to do, and which fits your needs better?
But you are paying for many attractions you won't go to because they hold no interest for you and you can do only so much in one day. Looks pretty expensive.
I haven't done an analysis of it, but knowledgeable posters here have said the Paris City Pass is an overpriced bundle of things you could buy separately for less money. The usual recommendation is to either get the Paris Museum Pass or just buy individual tickets.
I have found it hard work to make a major-city sightseeing pass pay off. I think they may work best for blitz visitors who have a lot of places on their to-do lists and not enough time to see them. If you find yourself in that situation and prefer to see a bit of (the highlights of) many places rather than have in-depth visits to a few places, a sightseeing pass may be economical for you. To make it pay, though, you'll probably need to keep your focus on visiting the covered sights you're interested in, not wandering off into picturesque neighborhoods to check out markets and the like.
