Man Frieza saga is freaking crazy. It shows off perfectly what I'd want more out of Super+. That saga is highkey intricate in terms of all the stuff that's going on. Super arcs are so straightforward in comparison.
I think largely what makes Dragon Ball Z great is not the deep plot/story, deep thematic details, deep characters (though the character development that is in Z is not bad), but the way things escalate. The progression of events.
With the way the power system works, it seems like it could only produce such stale results. Things are so binary in terms of who's stronger, what characters can last where, etc. But that makes me more appreciate what I think DBZ does well. Ever heard of limitation breeds creativity?
Think of a chess board. You have so many pieces that can only do one thing, but different things. (Probably not even a good example, it's more like if almost every piece moved like a rook, except some pieces are more limited in travel distance than others). When you have such a system, you gotta compensate somehow, and I think he ended up doing it pretty dang well. It's how he set up the chess board... And now that I think of it, maybe something more varied than my board of rooks is more warranted, it isn't all just about battle power.
You have the Frieza force who can only use their scouters to track, so that factor is taken advantage of to progress the events in an interesting way.
Even having the Zenkai boosts I think adds a cool variable to how things can play out, and Dende, and the Elder. The alliances. The dragon balls. Vegeta eventually learning how to track ki which I think was done very well. Honestly the dragon balls are a really good McGuffin sometimes. Each alliance has their own strengths and weaknesses that carry them on in a certain way that makes things interesting, and this plays into how the dragon balls are tracked too.
I think a key part to making these DB arcs good is how you take these constants and variables to interact and intertwine them in a certain way to further escalate everything. And I don't think Frieza saga does this without its problems, but god dang it does it freaking good overall. I can maybe see how people could think it is a slog waiting week by week, but reading through it all within a few days or so is great imo.
I can also see the complaints about a lot of it just being a wait for Goku, but for me I'm just getting enjoyment out of how this puzzle is constructed. You have these pieces that seem maybe not the most varied and interesting on the surface when we're looking at how power matters, but how can you put it together in a way that goes beyond the surface of this relatively rigid power structure? Surprisingly good.
