Which name do you prefer?
I prefer [name]Sebastian[/name] but it probably depends on the last name.
both are great. if forced, I’d pick [name]Sebastian[/name]
They’re both great (would make perfect twin names!) but I think [name]Sebastian[/name] is a bit ahead because it has a couple of good nickname options and also is more distinctive since [name]Elias[/name] is so much like the popular [name]Eli[/name] and [name]Elijah[/name] etc.
[name]Love[/name] [name]Sebastian[/name]! No contest!
I actually prefer just [name]Eli[/name] (E-lye) as a first name. One of my friends just had a boy named this.
I wouldn’t use [name]Elias[/name], just [name]Eli[/name]
I have to second the [name]Eli[/name] preference. [name]Elias[/name], too. I like [name]Eli[/name] as a nickname a lot, for any of the names, not sure about as a stand alone. Anyway, I’ve only ever met, or even heard about one [name]Eli[/name] ([name]Eleazar[/name], not [name]Elias[/name]) in my entire life, and he’s 24 now. [name]Sebastian[/name] seems a lot more common to me. I definitely understand the appeal of [name]Sebastian[/name], I guess he’s just not for me.
[name]Ah[/name]! Well - I adore both of them, but I ultimately pick [name]Sebastian[/name]. My son’s name is [name]Oliver[/name] [name]Sebastian[/name] [name]Finn[/name], so I may be a tad biased, but then again, [name]Elias[/name] is my DH’s middle name!
Definitely prefer [name]Sebastian[/name] 
[name]Gracie[/name]
I like [name]Sebastian[/name]
there’s more nn options, too!
I have a 7-year-old named [name]Elias[/name] [name]King[/name]. He goes by [name]Eli[/name], he loves his name, and we get tons of compliments about it. [name]Sebastian[/name] is very nice, too, but I always think of the hair product company by that name. But of course I’m biased for my [name]Eli[/name]…
I love [name]Sebastian[/name], and it’s my son’s middle name. He loves it, too. [name]Love[/name] [name]Seb[/name] as a nn.
“I prefer [name]Sebastian[/name] but it probably depends on the last name.” Snap!
[name]Sebastian[/name] for sure.
My vote is for [name]Elias[/name]!
[name]Sebastian[/name] is the better of the two. [name]Elias[/name] and all it’s variations are a little too meganame-ish for me.
