Yes, they give me very different impressions.
Raven seems like a teenage girl, probably in the 90s, slightly spoilt.
Robin is a young boy in medieval England who steals apples from the local orchard. I prefer the latter.
Raven seems strictly feminine to me, while
Robin is unisex, but I prefer it on boys.
Robyn is unintuitive and rather ugly. I think
Raven will continue to be quietly used, mostly by black parents, while
Robin will make a comeback as a masculine name.
