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 - Oscar is way too popular

Chichichochi · 19/11/2025 10:47

Seb Diesel 😎 Love it

Georgiepud · 19/11/2025 08:32

Sebastian I think.
A friend had a dog called Oscar.

Sebastian Diesel is a great name! Seb is cute and not try hard. Oscar is also a lovely name.
Both are really popular here.

Sebastian reminds me of sebaceous (oily) and Bastard, and I particularly dislike Seb and Basty!

Oscar is better but a little overused.

There are SO many lovely names outside the top 100 to choose from!

Seb

Yep, Seb 😎 love it

Sparklesandspandexgallore · 19/11/2025 07:37

Just seen I’m not the only one.

Sparklesandspandexgallore · 19/11/2025 07:37

I dislike Sebastian as it always reminds me of Bastard. Sorry but it does.

AliceMaforethought · 18/11/2025 23:49

Sebastian. Oscar sounds like a grouchy old man.

TidyAmberPoster · 18/11/2025 23:43

Both are lovely imo!

Sparklybutold · 05/11/2025 00:25

Between the two - I prefer Oscar.

Sebastian always sounds like bastard in my head.

theunbreakablecleopatrajones · 05/11/2025 00:17

Sebastian goes much better with your (characterful!) surname

Advocodo · 04/11/2025 11:30

Both lovely name but prefer Sebastian and Sebi for short.

TheJessops · 03/11/2025 12:59

I always loved the way Sarah Michelle Gellar says Sebastian in Cruel Intentions. And have loved the name ever since! I also like it in an English accent.

Oscar is perfectly lovely name, but a bit boring and common. Also Diesel is a cool surname but Oscar Diesel sounds like you are getting the phonetic alphabet wrong.

Marmalade71 · 02/11/2025 09:52

Sebastian definitely

TappyGilmore · 02/11/2025 03:43

Both very popular names and I always prefer something a bit more unusual, so I’d probably say Sebastian just on the basis that it’s slightly less popular.

Seb Diesel actually sounds quite cool!

Star965 · 02/11/2025 03:37

Both names are lovely. I think Sebastian goes better with your surname.

LivingTheDreamish · 01/11/2025 19:52

Fab surname! I prefer Sebastian I think. Oscar always makes me think of "the Oscars" and it puts me off the name. Also Oscar + Diesel kind of flow into each other when said together.

MasterBeth · 01/11/2025 10:29

Sebastian Diesel is a storybook name.

captainoctopus · 01/11/2025 09:15

Thank goodness I was a girl... if I'd been a boy my parents were going to name me Roger Sebastian.

(Sebastian on its own would have been OK 🙂- though I prefer Sylvester).

timoteigirl · 01/11/2025 09:05

Sebastian. Classic beautiful name.

Oscar. Wilde. Our dog. Doesn't sound as good as S.

Gilmoregirl21 · 31/10/2025 09:12

Sebastian definitely! It was top of my list but I couldn't get my husband to agree! He'd have been Sebastian Oliver, or Sebby for short. So cute 🥰

Squirrelmirrel · 29/10/2025 16:24

Both names have a very different feel. I do quite like Ozzy that comes from Oscar but I've really gone off Oscar which is strange as 10 years ago it was on my list for DS1. I think it became a bit too popular and now I've known lots of dogs that are Oscar. For me it kind of suffered the same fate as Bella in that sense.
Sebastien is more serious, I really like Seb, I think it's quite cool.

Yamamm · 29/10/2025 14:14

I think the loose rule for a two syllable surname is a one or three syllable given name. For flow. So John Diesel. Christopher Diesel. Not Michael Diesel.

John Diesel is so cool!

muddyford · 29/10/2025 14:00

Sebastian. I know several dogs called Oscar.
