What is the ultimate space marine?

[unicore]

Hello, this is my first post, I recently got a set of Privateer paints after not having paints for many years, and will be painting some old minis I have as well as getting a few. I have been making some 3D models (3d "Sculpting") and think there is a lot to learn from miniatures. Anyway, on to my question, I have been going through hundreds of models looking for a space marine miniature to paint, and not really sure what I want. What is your pick for the ultimate model that really captures space marines?

For example, one I like is Pedro, but the top of the helmet and some other details bother me. Another to consider is Artemis, the larger scale would make for a nice display.

to each to his own, but atm I think the DW-Artemis looks the best followed by some other DW ones from the overkill box.
Also the terminator Lysander stays a favorite.

Hard to pick but this one is the one I want to paint the most right now. https://www.games-workshop.com/en-US/Ulrik-The-Slayer

Definitely a nice model.

Good picks,only thing about deathwatch is the silver arm seems like an over used fad and doesn't look classic, I guess I could just mod it or use different colors.

Well I got one of these, sealed, on ebay. Not new hotness but probably one of the best "normal" marines. I'm going to try upgrading him with some fancy parts and base, right now trying to figure out what to do with the boring (plastic) right arm.
