Help me select a Space Marine Chapter

I always have a tough time deciding on a chapter to work on. I managed to narrow it down to a few that I liked but I was still left with several to choose from.

The candidates are:

• Celestial Lions - like the doomed fluff; not much of a future for them though without a miracle...

• Space Sharks - like the paint scheme and would be good for the Badab War.

• Crimson Tigers - DIY using Argent Tiger marking.

• Warrior Adepts - like the color scheme; quartered red and blue with company color shoulder pads.

• Death Knights - like the name and the knights in space concept. I've got a thing for surcoats.

• Exorcists - like the fluff and coloring. I have a thing for dark reds too.

So I figured I'd try sculpting up each of the chapter's chapter markings on the shoulder pads and select the one that looked cooler than the others. Take a look and help me choose by letting me know which one you think is the best of the lot.
