I like both! [name_m]Cyrus[/name_m] gives me sunnier, brighter vibes, while [name_m]Silas[/name_m] feels slightly darker, forest-y, mystical, but grounded too.
I associate [name_m]Cyrus[/name_m] with the book Martyr by [name_m]Kaveh[/name_m] Akbar; [name_m]Silas[/name_m] makes me think of [name_m]Silas[/name_m] Marner by [name_m]George[/name_m] [name_m]Eliot[/name_m].
I think I prefer the feel of [name_m]Cyrus[/name_m] for me
