If you'll be sitting in section 257, know that sitting in rows higher up is definitely better because of the dimension of the bullpens in left center field. I thought it was cool that the Angels and Tigers bullpens were adjacent to each other, giving fans out here some cool sights and sounds. But the bullpens made it harder for us to see the furthest parts of the outfield, especially the warning track. Imagine having to rely on the reaction of other fans to know if either outfielder caught the ball or not.
Also, this isn't the best spot for viewing either scoreboard. The main one is in upper left field and you can make it out pretty well but the 2nd scoreboard will be behind you when seated in section 257.
So if you must sit here, shoot for seats past row V. Only my opinion though but I think I've been to enough Angels games in the past to know where the most ideal places to sit are at this stadium.
