If I had to pick a top five from your list, it would definitely be [name]Felix[/name], [name]August[/name], [name]Micah[/name], [name]Julian[/name], and [name]Hugo[/name], hands down! They are all handsome with a retro and yet modern feel. Here’s some thoughts on the rest of your list:
[name]Abram[/name] - This name has always seemed a little abrupt to me. I prefer the full [name]Abraham[/name].
[name]Archer[/name] - ooh, I really like this one! [name]Archie[/name] is an adorable nickname, and [name]Archer[/name] is much cooler and more accessible than the slightly stuffy [name]Archibald[/name]. It does seem a teensy bit trendy though because of the rise in occupational surname names.
[name]Ari[/name] - cool
[name]Asher[/name] - such a nice meaning combined with a cool, naturey nickname ([name]Ash[/name]) makes this name nice, but I think you have some better options
[name]Atlas[/name] - definitely an “out there” choice, but I think it would be cool to use this.
[name]August[/name] - [name]LOVE[/name]!
[name]Beau[/name] - ehh, I know a few teenage Beaus, and they are all kind of cocky, jocky jerks.
[name]Byron[/name] - While [name]Lord[/name] [name]Byron[/name] wrote stunning poetry, I’m afraid this name will be swept up in the -on trend.
[name]Charles[/name] - nice
[name]Elliot[/name] - I like this, but it seems like its heading towards the girls
[name]Felix[/name] - [name]LOVE[/name] [name]LOVE[/name] [name]LOVE[/name]!
[name]Henry[/name] - like this, but its becoming popular
[name]Homer[/name] - all I can think of is the Simpsons (despite the epic poet)
[name]Hugo[/name] - another [name]LOVE[/name]! Its so handsome and retro, and its also multi-cultural since it can easily transition into a Spanish name with the pronunciation of “[name]Ugo[/name]”
[name]Julian[/name] - [name]Love[/name] it! Handsome to the max!
[name]Leo[/name] - like
[name]Micah[/name] - I really like [name]Micah[/name] - its such a cute alternative to [name]Michael[/name] that I believe is underused. (have you considered [name]Mekhi[/name]? [name]Mekhi[/name] Pheiffer (sp?) is such a handsome actor that name becomes handsome to me just from looking at him )
[name]Nathaniel[/name] - a bit dated for me
[name]Oliver[/name] - nice, but popular
[name]Sullivan[/name] - I like it, but I’ve never been fond of [name]Sully[/name]
[name]Theodore[/name] - I love how handsome this is, and [name]Theo[/name] is just a perfect nickname.
[name]Valentin[/name] - [name]Ever[/name] since seeing pictures of [name]Ricky[/name] [name]Martin[/name]'s adorable twin boys in People magazine, I have been swept up in the handsome cutes of [name]Valentin[/name] and [name]Valentino[/name]. [name]Just[/name] be prepared for teasing of “[name]Valentine[/name]”
[name]Winter[/name] - feminine to me
[name]Wyatt[/name] - I like it, but I feel like it is a bit dated
[name]Hope[/name] my comments help!
