Gotta cosign.
I rewatched the series last year and have to say from start to the end of Frieza saga is the definitive DBZ arc. Its such a complete, well thought out story compared to the rest of the series. Villain encounters were way better. Over a decade later and I'm still
at the amount of effort it took to defeat Vegeta. And the shyt that went down on Namek was amazing. Finally learning everyone's back story was some heavy shyt. Vegeta's heel-face turn. Racing for the dragonballs, giving the title relevance. Frieza pompously terrorizing everyone. shyt was just
all-around.
Android Saga started off great but soon devolved into empty showcases of power ups, with Cell and Buu Saga continuing the trend. Just a collection of "moments" with no substance. Not to say they weren't good moments, cuz there are many favorites, but it doesn't stand up to the earlier sagas as a whole. Not to mention inconsistencies everywhere. You can tell Toriyama was forced to continue after Frieza's death due to the popularity of the series.
