Every piece of good star wars media, has had, without fail, an absolutely top tier droid companion. Like over the years we've gotten so many great original droids. (Won't be putting clone wars on this list cuz there's no focused droid sidekick throughout besides R2 and 3PO from what I can remember.)
Andor : B2emo
Fallen Order games : BD-1
KOTOR : HK-47
Movies - R2, C3PO & BB-8
Rogue one : K-2SO
Rebels : Chopper & AP-5
Bad Batch : AZI (Introduction in clone wars)
Mandalorian : IG-11 & R5
Ashoka : Huyang (Again, introduction in clone wars)
Kenobi : LO-LA59
Skeleton Crew : SM-33
Even Acolyte had Pip although he's more of a self aware tool i guess.
Like no matter the quality of series, the droids are always awesome.
