I like the 71 slightly more than the 70. Also wish 71's came in sublime green or lemon twist.
71 with the dual headlights and billboards may be a little less likely to be confused as a Camaro with less knowledgeable car people. Sit in the stands at the races or a car show and listening to someone call a 70 Cuda a 69 Camaro is always entertaining. Doesn't seem to happen as much with the Challengers, but those Plymouth E bodies trip them up for some reason.
I had a 70 Cuda, Ed funny car body I made into a door car, about 4” narrower. It had the Mopar decal at top of windshield, some dude came over and asked why I had Mopar on a Camero? He was kinda pissed when he realized it was a Cuda. We laughed at that all nite!
