I apologise if I'm too harsh at times- :)
Aiden- Prefer Aidan. Nms, but definitely the best (and original) of the -ayden trend.
Aeson (ace-in)- Ace in sounds like a poker term or something.
Axel- Reminds me of a car.
Andrew- Okay, bit boring now.
Angus- Reminds me of the cat from a book I read.
Ansel- Hansel and Gretel, not a fan.
Anthony- I know someone called Anthony! It's quite a nice name.
Aramis (air-uh-miss)- Love this, just reminds me of The Three Musketeers. But I'd say A (as in Apple)-ruh-miss.
Aras (air-us, or r-us)- Instinctively I'd say A (as in Apple)-russ, but if I heard the other pronunciations more, I could come round to them.
Artemas- Love this. Glad you used the Artemas spelling. I wouldn't use Artemis, as (despite Artemis Fowl), it's not only a girls name, but the name of a goddess. As far as I know Artemas/Artemus means gift of Artemis, so can be male (or female).
Asher- Not a fan, Ash hasn't got great connotations for me. I prefer Archer, or Archie.
Ashton- See above. Ashton actually sounds like a ton of ash.
Atticus- I have a friend whose name is said like Attica (but spelt differently), and I just can't bring myself around to liking Atticus.
So, my faves are:
Aiden: I like it, but IMO way to trendy now with all the spellings of Aiden and the rhyming names like Kayden, Brayden, Hayden, Jayden etc
Aeson (ace-in): Don't like it sorry
Axel: I quite like Axel
Andrew: I like it. It's a nice classic with some great nickname options.
Angus: I like Angus.
Ansel: I don't like name Ansel. Not my taste.
Anthony: Anthony is an okay name.
Aramis (air-uh-miss) Don't like it. Not my taste
Aras (air-us, or r-us) Don't like it. Not my taste
Artemas Don't like it. Not my taste
Asher I love the name Asher.
Ashton: I love the name Ashton
Atticus I love the name Atticus. One my favourite character names.
Aiden - Nice. Will probably end up being very dated in the next 10 years or so, though.
Aeson (ace-in) - Dislike
Axel - Handsome, but I don't like the Axl Rose association
Andrew - Not my favourite classic, but a good solid name
Angus - Very Scottish. Like a cartoon Scotsman name. Quite handsome, though.
Ansel - I've never heard this before, no opinion really. Ansel and Gretel jokes could get annoying.
Anthony - Very handsome, although I don't like the usual shortenings
Aramis (air-uh-miss) - Ever so slightly pretentious, but nice enough
Aras (air-us, or r-us) - Noooo! Sounds way too much like arse, especially as r-us. He'd have to stay away from the UK and Ireland.
Artemas - Wasn't Artemis a goddess? This looks like a misspelling of Artemis, so I think it's a slightly strange name for a boy?
Asher - OK
Ashton - I don't like surname names, but it's OK
Atticus - OK
In conclusion, I think we have pretty different styles! My favourite is probably Anthony, and least favourites Aeson and Artemas.
love - Asher
like - Aiden (although I prefer Aiden), Axel (middle name only), Ashton
neutral - Andrew, Anthony, Aras, Atticus, Ansel
dislike - Aeson, Angus, Aramis, Artemas
suggestions, Caden, Hanson, Anson, Tobin, Tobias, Torin
I like Asher, Ashton & Atticus. The others aren't my style. I do prefer Archer, though, I feel like it's more substantial than Asher. Have you considered Abel?
