Punisher is a damn decent size, and hulk looks F-ing huge, has anyone done the actual units size differenec between 1/4 and 1/5 scale, if you look at the pic of spidey and hobby you can mainly see the difference in the hands and head, but having a pose where the body is all hunched or folded doesn't help in comparing sizes either.
In terms of height it's a couple of inches between 1/4 and 1/5. But there is a noticeable difference to the bulk of the sculpt.
1/5 scale is 25% smaller than 1/4.
Mixing scales costs sideshow a purchase from me. I won't buy 1/5.
