Your dislike for Oda character designs is understandable.

But i have to disagree with your assumption that Oda makes this character looks stupid for the sake of being different.

At first i was a bit bothered by some of his characters design too (Robin nose odd shape for example), but i eventually learn to ignore it and focus on the story.

From my perspective, the reason i always like One Piece much more than the other Shonen is because it seems like Oda is creating an entire world with his writing rather than a story following the main cast.

Yeah a lot of One Piece characters looks odd, but in a sense that mirror real life. I'm pretty sure there are plenty of real people that you would find to be odd looking too, not everybody is attractive.

Franky looks extremely silly but knowing that doesn't make his background story any less sad. Gecko Moria is incredibly stupid looking but that doesn't make the things that he is doing any less twisted. I suppose the old proverb "Do Not Judge a Book by Its Cover" applies here especially since the excellent writing in One Piece makes a lot of these strange looking characters a lot easier for me to relate to than "normal" ones from something like naruto.

That being said, it is a pity that you are missing out on a great series but if you dislike his art style than i doubt you will be able to fully enjoy the series.
