I think I've experienced the difference but I'd have to go do some verification and I am out of juice today and it is only one more day after that for us all to see the final version.
IIRC, using the Friends spell actually led to a -5 reputation with the target after the conversation ended and Charm Person didn't. It could be that those were different builds though.
In PnP Friends makes people upset, while charm person makes them annoyed/offended. Bottom line difference is that friends is more likely to get you punched, so be careful using it on people you would like to stay friends with (oh the irony).
