Well, these are arguably the BEST DBZ figures made thus far. All other DBZ toys made in the past 20 years literally pale in comparison, when you take into account the attention to detail, multiple accessories, hands/faces, articulation, etc. these babies come with so it's no wonder these are highly sought-after collectibles, and Tamashii-Bluefin know this I'm sure. Even the worst-looking DBZ Figuart is still better than the best-looking DBZ figure of the past decade. Everytime I look at Normal Goku's face I say to myself "damn, they really hit the nail on the head, this is him, like he literally jumped right out of the anime into my hands." Just flawless. Whereas you look at the Gokus released in like 2000, while "good" for it's time, no other company managed to get the exact facial features down, they would always look off.
The only other thing that can match S.H. Figuarts DBZ in terms of likeness to the characters are statues.
