Atm, in current slightly modded configuration, my top 3 are ANV, ATE and ED9 (brass). I honestly can`t rate one over another because they have different sound signature and music focus.
ATE is great all-rounder while ED9 is more suitable for EDM/pop-rock and ANV for acoustic/instrumental/vocal.
Though, my opinion might change after I finish modding them all.
About EDSE, I and my friend (who is using them most of the time) have burned it long time by now and I still find highs splashywith SSsss sibilance in vocals and bass department is still lacking littlebit. Maybe I should try to mod them sometime but they are not so appealing for that in my eyes/ears.
GR wasn`t bad or good for me but it was totally different from other KZs with its quite intimate/foward and
Λ-shaped soundstage. They were great for oldschool rock imo.
R35 was very similar to Piston2 when its harsh highs are removed by foam mod.
If someone pointed gun to my head - I would say ATE is best KZ IEM at the moment. I`m so sorry ANV & ED9 ;( !
