Is koby the worst powercreep in one piece?

It is mind boggling to me and i honestly hate how oda has powercrept koby in the most bs ways in the series. Dude went from fodder to arguably tobiroppo or just below tobiroppo level in the same time frame as luffy just because he ‘trained under garp, meanwhile luffy practiced like a mferrrr snd beat so many strong opponents that koby is now considered stronger then, and oda is heading the garp to luffy in modern day and it makes no sense, i get it if he made smoker be that guy, but to make koby and powercreep him with bs powerups to be that strong has to be the worst case of bs in the series imo
