I don't enjoy lnfns, so Wyatt is out. I love William and most of its nns, but I totally dislike and despise Liam. Bottom 2, therefore.
I actually like Anders the best, but only with a Scandinavian pronunciation, which is improbable. I find Henry dull and boring. So that seems to leave Declan and Ronan as my top 2! I don't think I'd ever use either of them, but they're OK.
