Need advice for gear

Guys should I buy Castle Breaker's Battleplate or Ymirjar Lord's Battleplate for my furry warr and why?

Only not "Tier" gear you might need to buy for Emblems of Frost (EoF) is cloak.
For chest you literaly must buy Ymirjar plate, as it is one of four pieces if gear that are crucial for your class to perform well

Thank you for your answer
