[name_u]Finn[/name_u] has taken off here, for good reason 
I really like [name_m]Gavin[/name_m].
finn is definitely my preference. I would worry heavily that my child would be bullied with the name gavin. 
[name_m]Gavin[/name_m]. It feels more rugged and boyish, and I could totally see it making a comeback.
[name_u]Finn[/name_u] is creeping into overused territory, I just can’t get on bored.
[name_m]Gavin[/name_m], because it is less popular. It has has a friendly, rugged, outdoorsy feel to me. [name_u]Finn[/name_u] feels like a nickname….
Oh wow, we have very similar taste. I love both [name_u]Finn[/name_u] and [name_m]Gavin[/name_m] a lot. I think it depends a lot on which one melodically flows better with your last name. One syllable or two syllables. [name_m]Gavin[/name_m] is on my super short list for my upcoming son, and [name_u]Finn[/name_u] would be except for the fact that my older is [name_f]Fiona[/name_f] and I think they’re too similar. If she had been a boy, she’d be [name_u]Finn[/name_u].
I like both, but prefer [name_u]Finn[/name_u].
I prefer [name_u]Finn[/name_u] to [name_m]Gavin[/name_m] but like both. Also just throwing it out there. [name_u]Griffin[/name_u] has [name_m]Gavin[/name_m] vibe but nickname [name_m]Fin[/name_m]
[name_u]Finn[/name_u]!
Definitely [name_u]Finn[/name_u], it feels more fresh and i prefer the sound
