I love Oliver. Liam is a gem, too, but not as a legal firstname; I prefer it as a nickname for William (or a similar name/variant).
As for the others... they are all on my mental dislike list, more or less.Blake doesn't sound like an incredibly professional, strong option. It is a bit awkward and goofy.
Ronan is a name that I truly wish that I harbored a fondness for. I just can't bring myself to fully accept its use in the real world.
Wyatt has been turning my stomach since I was a child. Its attraction and popularity will forever mystify me.
And
Miles is another name that I genuinely want to adore, but simply cannot. I admire
Miles and
Ronan used as literary characters, though.
Best of luck,
- Francesca
