Err I would still play Paladin, even if they would suck. I simply like the flair of the class.
I also play female Highelf and she's chaste and if I could, she would get an unicorn as mount; and an all white armor.
I also didnt pick Vengeance. Though I might turn Oathbreaker if it turns out its too much of a PITA to stay true to the Oath. I heard rumors about that.
Paladin is one of the classes that are a LOT more interesting to play now than back in BG1 and BG2.
Did you do your homework? Fighter has 3 attacks, superiority dice and action surge.
Superiority Dice is only a thing for Battle Master Fighters, though.
