Just to play Devil's Advocate, since I am a huge fan of Filoni's Clone Wars series, Clanker feels the most weird because it was created to be used as a slur in the same way the Allied forces had slurs for Germans and Japanese in WW2. I can understand why some people might have moral grounds against using what is ultimately a proxy of real life slurs, especially if they were ever a recipient of that kinda discrimination. Sure, it's a fantasy, and I think from a standpoint of "The Republic is experiencing moral decay" it's interesting for the story, but it was always a lil fucked up that the kids show thought hurling slurs was such a fundamental part of war that they needed to invent a new one. It'd probably be better if we didn't teach children that.

It's also kinda a weird slur to use against AI. The droids are called clankers because they clank, it's like an onomotopeia. LLMs don't clank at all.
