In what ways is it better? Security margin or something? I thought Speck has held up pretty well to cryptanalysis (unlike you I'm not in the security field so maybe I'm wrong).

I quite liked the remarkable simplicity of Speck. Performance was better than Ascon in my limited testing. It seems like it should be smaller on-die or in bytes of code, and with possibly lower power consumption. And round key generation was possible to compute on-the-fly (reusing the round code!) for truly tiny processors.
