If you want the best way to enjoy DBZ, build a time machine, travel back to the 1st airing of your preferred dub and watch it on a daily/weekly basis. Then you have your best DBZ experience.
If you want the experience closest to the author's intent, read the manga.
And if you read the manga, you will realize that
- Dragonball is a very light hearted story which started as a comedy. The Freezer arc and Cell arc are the most serious parts of DB and still are not as dark in the manga as in the anime. That's why many don't like the Buu arc.
- Dragonball is a clusterfuck of a story and shouldn't be taken too seriously. Toriyama was making shit up on a weekly basis. There is no long term story in DB.
- just. how. much. filler. there. is. Most famous example: Bardock
- Goku is a battle hungry idiot and the anime made him more into an hero than he is. Translations | WIRED Japan 1997: Akira Toriyama interview:Btw, Toriyama is talking about the japanese version. To my knowledge the english dub made him even more an hero.
So yeah, DBZA is actually a pretty good way to enjoy the "story" of dragon ball (z). And if you read some side information, you will realize just how much love they put into DBZA. And when it comes to long time planning and pay-off, DBZA is the best version because the other versions are just anime adaption of the weekly realeased manga.
Kind of a miracle that this mess of a story turned out to be the most popular manga in the world...
