TBH it's not a high bar if you ask me. Aside from EU wank that sometimes made him almost superhuman, Boba Fett was a guy who had a cool armor, said one cool line then got unceremoniously taken out. Were it not for said iconic armor I daresay hardly anyone would have given a shit about him, "bounty hunter" wasn't just his job, it was his entire personality.
Din is an actual character, maybe not the most original ever made but very well executed. He's just way better than Fett at anything, aside from maybe having a less cool armor but even then that's debatable.
