Stuck between Oscar and Sebastian… which do you prefer and why?

My Husband and I are expecting a baby boy in April and we’ve narrowed it down to two names we really love: Oscar and Sebastian

We’re completely torn. I’d love to hear what vibes each name gives you, and which one you think fits better with our last name (Diesel)

Thanks so much for helping us decide — we keep going back and forth.

Sebastian.I just don't like Oscar.

I like both but Sebastian is top for me. I wish I had used it for one of my 4 boys 💖

Oscar, lovely name that I think is underused. Sebastian is a bit of a mouthful to say (not against long names but that particular name doesn't flow easily to me), the one Sebastian I know shortens it to Sebu, which just makes me think of that Veggie Tales song 'the song of Cebu'

Underused?? In the south east every baby group I went to there were at least 3 Oscars, nursery and reception there are two in my DCs class

Sebastian. Definitely

And there was me wondering if you were F1 fans!

Both are lovely. I’d choose Sebastian - sounds good with your surname, it’s less commonly used than Oscar and I love the nn Seb.

Sebastian on the basis that there are loads of Oscars - four in my DS’ year at school.

Oscar, it’s lovely. Sebastian will probably get shortened to Seb and any one syllable name would be too similar to Vin Diesel for me.

Love Sebastian Diesel - super strong name. Not as keen on Oscar Diesel - same amount of syllables in both names doesn’t flow as well. Also think of Oscar as a cat’s name sorry!

Seb

Usually I have a strong preference for one on these sort of threads but I love both! Really nice names and due a comeback. Sebastian reminds me of The Neverending Story and The Little Mermaid, and Oscar of course reminds me of Oscar Wilde. 😍
