I guess scale if you can count that as a positive. A lot of pre-TS is predicated on the idea that Oda can manage the scale of his story when everything starts to come together. Imo that scale of meta narrative that involves the major characters (Yonko, WG/CP, Marines, Shichibukai, Supernova, etc) is still unrivaled and how he's woven all of those characters into each arc is great.
What isnt is the sheer number of arc related characters beyond this lol, but I guess islands need inhabitants so what are you gonna do
I think how he's moved on from Kaido/BM and to Bonney/Kuma/VP/Blackbeard /Shanks/ Kizaru/Sentoumaru/Gorosei, etc. For Egghead is what worked for me. What isnt is adding 9 VAs that did nothing the entire arc and Serephim and Lucci/Kaku/Stussy and Dorry/Broggy/Oimo/Kaashi. Thats where it starts to lose me but again, I get it. You create the problem of having a million characters, you want to use them and end their plots.
