I don't have detailed notes like some of the others, but that's probably the best info you'll get. Getting statistically valid information would require an apples to apples comparison of two identical websites targeting the exact same keywords - one targeting 100% organic, and one targeting PPC with the entire site no-indexed so it doesn't get any organic traffic (and they'd have to have the exact same rankings for each of those keywords.)

I will say that there are a lot of cases where you're not even allowed to get PPC traffic, but that traffic is as laser targeted as possible.
Those examples include neighborhood level searches where the visitors are HIGHLY qualified visitors, but they represent too low a volume to even be able to bid on via PPC. Even better examples include specific property searches which are impossible to bid on via PPC, but quite easy to rank for via organic.

That's definitely a case where organic takes the cake.
