>>7763045if we're talking about 2017 Pennywise, they're all pretty good. I find the legs on them kind of awkward to pose but it's nothing major. The major issue with the spider legs one is that the spider legs weigh down the elbow joints because of the weight, so you have to be mindful of how you pose it.
Wellhouse is a good choice though if you only want one. Really all you have to do is decide what your favorite look for Pennywise is since NECA basically covered them all from the first movie. It is worth noting though the paint on the very first release feels a little lacking compared to the later releases.
