HiroToon 4 and Jason look completely different, though their builds are similar. Jason’s in the pink shirt.
Edit: Corrected Hiro 4 to HiroToon 4. HiroToon4 and Jason are both 3D Universe products.
They look VERY similar. The only differences between the two are the eye and overall face roundness. Everything else is practically identical.
To my eyes Jasmine & Jason are very western toon style whereas Aiko & Hiro are more anime/mange style. However having said that Aiko & Hiro are still a little westernised and don’t quite capture the unique anime/mange style. I think Manihoni’s morphs (at Renderosity store) are much closer to the anime/manga style.
If you refer to the actual A4 & H4, then you’re half right. The Gen 4 versions of the DAZ 3D Anime couple are, in artistic spirit, different from their Gen 3 pioneers (Gen 2 if you want to be technical with Aiko) in that where A3/H3 were more of the actual typical Anime/Manga style as Hitomi is today, A4/H4 are more sophisticated and in the styles of contemporary video games and Japanese Pop-culture. However, because of this, people have commented, myself very much included, that the way A4 & H4 were supported made them look too posh and snooty while A3 & H3 felt much warmer and friendlier. Hitomi recaptures that warm, cute Anime Girl feel that we missed back in Gen 3, and her sales prove it!
That shirt does look to be basically the exact same article though. It’s interesting to see the evolution of the characters and clothing from the different 3DUniverse characters, making Jason and Jasmin (and Amy) almost a greatest hits of aspects of the two versions of the Toon Aiko & Hiro characters plus Skye.
Speaking of Amy and character comparison, I hear that some Toon fans here attribute her to The Girl for reasons I don’t quite understand myself. Maybe it’s simply the fact that they’re both Toon girls and Jasmine is already seen as AikoToon 5.
