Gigabyte z87x ud3h or Asus z87 plus or pro. Those mobos have better stability and reliability than ASRock mobo. ASRock is cheaper but Gigabyte or Asus has better life.
Now it's all ur choice , depends on your budget.
I hope it helps.
You have not used Asrock recently? They have the same component suppliers as Asus. The only thing that make could possibly be worse on an Asrock board is that the PCB is generally thinner.
