I always went with the default Shepard. I've never been too interested in character design in these types of games so that won't affect my enjoyment of the game much. Downloaded the game overnight so I'm hoping to get to crack this one open tonight. Just finished Horizon: Zero Dawn Sunday night too so I'm good to go!
BTW: Horizon: Zero Dawn is a very fun game. If you like the Uncharted/Tomb Raider style of games that one needs to be on your must buy list. There are things that Uncharted does better (climbing being one) but the story is awesome.
