I agree with sasook here, even in that quote snakeee says "Still, this stage is useful against certain characters that you don't want to give much room against" and Link is one of those characters you don't want to give space.
Even if LC was a bad stage for ZZS, it's also a horrible stage for Link. He already has a horrible recovery with limited options, why pick a stage that has weird edges that his zair loves to avoid. And yeah, snakeee even mentions it as a great stage in that second quote.
Anyway, Castle Siege or Japes seems better. CS is great for spacing (and the first part above the castle is great for zair and bombs, in the castle keeps you from getting gimped). The advantage on japes is that you make her recovery much more predictable since she can't go as low as she likes because of the water.
