Personally, I really dislike
Renee. I think it sounds whiney and dated and it's one of a very few names that I actually get put off of the person when I hear it in real life (names like
Whitney,
Abigail,
Sadie and
Sebastian are amongst the others...) That doesn't mean it's a bad name, I just very much dislike it.
Renée is the classiest of all possible options, although I don't find it a very classy name in the slighest.
Renae is kind of bad,
Renee is middle-ground. Sorry! I don't mean to be mean.
