There are many Spartans throughout the lore of halo, while it being a spartan 2 or spartan 4 who is your favorite Spartan?
Linda-058 has always been my favourite ever since I read Halo: The Fall of Reach.
Linda. Because she is a really cool sniper.
Emile because he was a badass and went out a badass.
Buck just cause his cool, calm, collected voice when he is your announcer in h5. I actually say to myself sometimes: “Damn you’re good!” Or even “That’s a double” or “and That’s a triple!” Yeah really good stuff.
A while back I became curious about Spartan 116 and why we never hear anything about them. I asked my self a bunch of questions and then decided Spartan 116 would be my favorite.
John-117 because he’s the master cheif what more can I say.
Fred-104. I can’t stress this enough times. He is my favorite and there are many reasons for him being awesome, even including his potential to be the permanent main protagonist.
Either Carter-A259 or Jerome 092. I’d say Buck but I just like him as a character overall and I do consider him one of my top 5 favorites. I also like Chief but seeing how he’s the main character of many of the games, I won’t go with him
For me it has to be Masterchief (even if it is a obvious answer)

For me, it would have to be the Master Chief, John 117
Love his story from the very beginning to the end, taking a final stand for humanity and finishing the fight; referring to the end of Halo 3, as well as where the story has been taken following Halo Infinite
My second favourite would have to Daisy, Spartan II 023; loved her story too, and was great to see it in the Halo Legends series 
I would have to say Samuel 034. He was the strongest of the Spartans and a good friend to John 117. He died at the age 14 because his armor got a hole in it during a fire fight with the Covenant. I’m the end he stayed behind to make sure a bomb went off on the Covenant ship. Imagine if he would have lived. Let’s not forget about Kurt 051 either. Just go read “Halo: Ghosts of Onyx to learn more.
For me it’s Either Spartan-B312 (Noble Six) or John-117, the Masterchief. they’re the only two spartans given the hyper-lethal rating, which makes them so cool. I especially loved the way Six’s death played out, going down with a fight.
Noble six because me 
Noble six and the Master chief
I will say Master Chief is my favorite Spartan in the Halo video games.
I feel like Jun is under appreciated. However I have to go with 117. Always been my favorite Halo figure.
The chief of course
Emile or MC
