Wow, this one's tough! Arthur inevitably wins for me because it's a family name for me. I like his retro vibe. Rhys is simply lovely but I adore Arthur! :)
And yes, I think most of uus Mountaineers are a little braver than the average with our boys names. I know 'I' am! :D
I voted for Rhys. I like it....don't love it... but I just don't find Arthur appealing at all.
