Some names that we like are
[name]Ryan[/name]
[name]Bryan[/name]
[name]Ethan[/name]
[name]William[/name]
[name]Cameron[/name]
[name]Cole[/name]
They’re both nice, friendly and handsome names. Unfortunately, there are a lot of girls being named [name]Ryan[/name] now, so it will probably feel more like a unisex name by the time your son grows up, which means it might have a different vibe than I think it has on men with that name now. (I wonder if it might sound sort of like the way we would hear [name]Leslie[/name]?)
So, I voted for [name]Bryan[/name]. But I actually prefer [name]Bryan[/name] spelled [name]Brian[/name].
(somehow, in [name]Bryan[/name], the y feels feminine to me)
Oddly, though, I [name]LOVE[/name] [name]Byron[/name] (y and all) - have you considered that as an option?
I voted for [name]Ryan[/name] [name]Michael[/name]. All though I do like [name]Ryan[/name] for a girls name I still feel it makes a great boys name. I mean that’s what it really is, a boys name. [name]Bryan[/name] I prefer spelled [name]Brian[/name].
My favorites from your list would be [name]Ethan[/name] or [name]Cole[/name].
Were [name]Ethan[/name], [name]William[/name], [name]Cameron[/name], and [name]Cole[/name] recently added? I would have voted for [name]Cameron[/name] if I’d seen it. So change vote from [name]Ryan[/name] to [name]Cameron[/name] 
[name]Cole[/name] and [name]William[/name]
[name]Ryan[/name] and [name]Bryan[/name]. I prefer [name]Ryan[/name] a million times more than [name]Bryan[/name], and I like [name]Bryant[/name] more than [name]Bryan[/name].
[name]Ethan[/name] and [name]William[/name] It is no contest here [name]William[/name] with all its wonderful nn’s is a clear winner. [name]Ethan[/name] on the other hand reminds me of ether (anaesthetic).
[name]Cameron[/name] and [name]Cole[/name] The beautiful [name]Cameron[/name], so handsome, always a winner. I just love [name]Cameron[/name].
To summarise
I love
[name]Cameron[/name]
[name]Ryan[/name]
[name]William[/name]
