Favorite mandalorian clans are

Mudhorn clan

Clan kryze

Clan vizsla

Clan wren

Wren because of Sabine one of the few that used the Darksaber in combat and won, plus she's an artist and one of the founders of the Rebels (or at least Phoenix squad part of it)

Wren or Kryze

I say Clan Kryze because they are the most important clan since Satine is the Duchess of Mandalore and she was an important person on the planet. She had a good perspective on the war. Plus she had good relations with Obi-Wan and Padme

I also do like Clan Wren as well

Mud horn: all others are cowards, traitors or honorless thugs, sometimes all three.

Wren isn't all three lmao.

Does Din Djarin have a specific Clan?

Yes the Mudhorn

Clan Vizla because they actively engaged in combat, making their clan members battle hardened and more effective than those clans who saw little action.

My favorite is Clan Wren because it includes my favorite Star Wars character and Mandalorian, Sabine Wren.
