I also did that when I fear that boss battle. Also you can shoot an arrow to stunt it, put the Zora mask and throw the blades. But that way is boring. I prefer in my latest playthroughs to just swim and attack him with the electrical attack.

You can aslo defeat Goth shooting it fire arrows while you wait at the entrance of the arena or Twinmold with light arrows at the tail.

To be fair, finding the right sword moves to defeat him was harder than any puzzle I've encountered in a boss battle.

That's because it is different from whatever we have being playing before. It was always like: you have to use the item you found in dungeon, stunt it and attack with your sword. Repeat three times and be happy. That's why I love Majora's Mask boss battles. You don't needed the dungeon item, and why I liked so much Ghirahim.

I liked playing against Goht with Fierce Deity Link.

You just stand there and wait for him, then it's all [insert Dark Knight Reference]

Odolwa and Gyorg are also easy but Goth is maybe one of the best boss battle in Zelda series. What bothers me is Twinmold. The best way to fight and finish as soon as possible is to use the Giant Mask and the Fierce Deity is useless.
