I believe it depends on your situation.

If you have been to Paris before AND like/love it AND don't see yourself getting there anytime soon AND really want to burn that award (not spend some $), then I would take the award at the Hilton CDG.

BUT staying in Paris is to me what makes the whole experience.

We stayed at a Holiday Inn Express* next to the Peripherique (Place D'Italie). While it took us 5-10 minutes to walk to the Metro, we were walking through Parisian neighborhoods, great for the feel and great for picking up cheap food items as we were outside the tourist areas (lots of local markets/restaurants). As noted above, you will not get this flavor staying at the CDG Hilton.

*We just stayed here through a last minute (three days before we left) hotels.com rate (over New Year's) for $71US per night. Every other place was outrageous price wise (nothing under $140US)
