>>9986502Super 7 used to be a vinyl toy company mostly, but in recent years they expanded into articulated figures. I own quite a few now and they are well-made and large figures. Whether they're worth the price is completely subjective. Certain ones feel not worth it, others feel like a bargain for the price (generally the bigger bulkier ones). The range of motion is generally serviceable, but not great. Sculpts and paint are generally very well done.
I think I can say that if you want articulated Spongebob figures, it's unlikely that anyone else will ever top these, aside from perhaps Super 7 themselves if they release future variants. It's a very niche market to begin with (adult collectors who want super poseable Spongebob toys and are willing to pay collectors prices for them), so if that's your bag, I'd say strike now while you can.
