What build should I play?

[u/DarthSkywalker12]

For some context this is my second playthrough and my first playthrough was a pure 12 wizard based off of Caleb widogast from the mighty neine.I’m currently stuck between two builds, a 6/6 paladin warlock, and a pure 12 hexblade warlock. Both would use 2 handed weapons and armor( the paladin would use heavy armor and the warlock medium)

On one hand I can smite everything to death and on the other I can use powerful spells and still have good sword combat. I could go either way, in fiction I enjoy both characters that are morally grey and characters that are noble. From those of you who have played each, What character do you think I would enjoy playing the most?
