Kubo outfits in Bleach are either kimonos or quite realistic street fashion. Outfits in Jojo are outlandish and not anything people choose to wear day to day, so while the Jojo outfits show a better sense of fashion artistry, at best they can just give some inspiration to outfits, in the same way that all the wacky stuff at Paris fashion show can. If someone dressed like a Jojo character, 9/10 times it would look ridiculous. Fashion is in the eye of the beholder, but most beholders would laugh a real life Jojo character out of the building, as long as they didn't also have the physique and thirst for combat as a Jojo character. As much as throwing out different ideas like Araki does it important for innovation, Bleach outfits are more often actually wearable as they are.
Not that I'm one to choose favourites, unless pressured to bullshit and pretend to have one. This is an interesting question though. I definitely try to get inspiration from anime, but lots doesn't translate well to real life or would be a pain in the ass (like the hair in most battle shounen anime).
