Way too long post that's spoilered for those that don't care about HSR.
[spoiler]
>1.1, SW + Luocha
Not very relevant in the grand scheme of things, SW was overhyped and mono quantum was a meme.
>1.2, Blade + Kafka
Blade was a solid sub-dps, DoT was always a meme.
>1.3, Dan Heng + Fu Xuan
First limited sustain, she was pretty good. Our Caesar, I think. Dan Heng did impressive damage but wasn't metawarping due to how SP hungry he was.
>1.4, Topaz + Jingliu
Jingliu was busted on release, Topaz ended up being good down the road. Honestly might have been HSR's Miyabi because she was braindead to use and did way too much damage by comparison. Pair her up with Blade and yeah you shat out damage at the time.
>1.5, Fofo + Argenti
Nothing notable.
>1.6, Ruan Mei + free 5* male Dr. Ratio
Our Astra.
>2.0, BS + Sparkle
DOT was always a meme. Sparkle was too niche.
>2.1, Acheron + Aventurine
Outclassed every prior unit on the DPS and sustain front.
>2.2, Boothill + Robin
Best support in the game at that point, still relevant.
>2.3, Firefly
Best DPS unit in the game, eclipsing Acheron.
>2.4, Acheron support
Acheron now eclipses Firefly again.
>2.5, Feixiao
Followup is now a viable team and gets shilled in content.
>2.6, Rappa
Firefly is now a benchwarmer for non-bosses because other content shills Rappa.
[/spoiler]
All of which is to say that the two are about the same. Difference being that ZZZ seems more willing to buff older characters right now but we'll see if that's relevant or just "+50%" to every multiplier.
