That is a tough question, because it depends on how you play the game. Are you roleplaying, powergaming, or something else? A build is generally designed to accomplish something, otherwise why fuss over it? Morals also may factor heavily into this.
This question is also impacted by any mods you might be using. For example, playing The Lost Spires & perhaps with companions like Vilja/Vonrica set to essential really changes how you play, thus how you build your character.
So, now that I have gotten off my soapbox
, I'll try to answer:
Roleplaying: Imp/RedGrd/Nord (Noble class: Knight/Pal, Crusad, Cleric,) Good
Wood Elf/Bretton (Thief/Robber/Assassin/Sorc/Mage) Evil
Freak (Orc/Khajit/Arg/Dunmer) Good or Evil
Powergaming: Bretton (Mage/Spellsword) Good
Wood Elf (Archer Thief) Good/Evil
Something Else? Varies. Most likely depending on mods/mood.
I agree with you that Bretton is one of the strongest races. The + Magic with +perks & no negatives is just too good.
