Definitely Jeffy's Parents.

Why are some videos more popular than others?

@BobSponge222 On every youtube channel, there will always be some videos that are just more entertaining.

@Junebug25 Jeffy's WiFi Problem isn't entertaining at all.

@BobSponge222 I agree, but some videos just get more popular that others.

Jeffy's Parents: An excellent video and definitely one of the best, though not entirely the best.

Jeffy's WiFi Problem: One of the worst videos of 2018.

Jeffy The Rapper 1: The best Jeffy Video I have ever watched.

Bowser Junior Goes To Disney World Part 2: It's a decent video, though Part 1 reigns superior.

Jeffy's Cellphone: Also one of the worst videos.

Smart Jeffy: Disappointing excuse of a Jeffy video.

@LancerWikiEditor agree with all but the last.
