Hard to choose between "The Two Faces of Squidward" and "Skill Crane" but I went with the latter

The Two Faces of Squidward is better because It created the Handsome Squidward Meme.

Imo

6. Squidward in Clarinetland: 1/10 (ATROCIOUS)

5. Chum Fricassee: 3.5/10 (High Very Bad)

4. Suction Cup Symphony: 4/10 (Bad)

3. The Two Faces of Squidward: 5/10 (Meh)

2. Skill Crane: 8 or 8.5/10 (Neutral or High Great)

1. The Lost Mattress: 8.5/10 (High Great)

Krusty Towers is my favorite Squidward episode from post-movie though.

Squidward! You're even more handsome now!

@PabloDG I didn't include it as I didn't want the poll to be too obvious

The one featuring Handsome Squidward.

@Jerico Y. I feel the same way. Both are good, but I like Skill Crane a bit more.

Skill Crane has always been one of my personal favorites so I had to vote for it

The Two Faces Of Squidward by far.
