These are the best servers to you? From all the players you mentioned only Pliskova and Rybakina would be in the "Top 20". In normal conditions Sabalenka also would be in that top..., but there's something wrong with her right now. Kvitova also was a good server, but she has lost the fire and I think she will retire soon. All the others players you mentioned (Muguruza, Vondrousova and Tauson) are just too inconsistent on that aspect. I can make a long list of players who serve better than those 3 players (Barty, Serena, Krystina Pliskova, Osaka, Brady, Keys, Krejcikova, Swiatek, Badosa, Samsonova...).
It shocks me how Badosa has improved her serve this year. Definitely, that's one of the reasons that explain her big success. She is the second player with more aces in 2022 (only Keys has did more aces than her), and her % of service games won and points won with 1st serves are also impressive. Both Görges and Bertens were also really good servers, as well as Venus, Lisicki, etc. Konta's serve was also something to be considered, but she has had too many injuries over the last years.
From all the players you mentioned, the player who definitely has a big dependency on her serve is Pliskova. I have seen her losing against really weak players only because her serve didn't work. I wouldn't put her in the same category than Rybakina, Kvitova, Sabalenka, Tauson..., as you did. I have seen Sabalenka winning matches against good players despite doing like 20 double faults (I never have seen Pliskova doing such thing).
Georgina Garcia Perez definitely can be on that list. She's not on the same level than Pliskova (of course), but she depends on her serve in the same way that Pliskova does on hers.
