Bite your tongue!
As much as I thought 4" scale was the bees knees, the sweet spot for detail and still having vehicles... it still is. Except the 6" gives us a lot more detail on the figures and have an awesome shelf presence. And now that I'm down the rabbit hole on my Mega Joe project, I love the tiny scale for more vehicles, better scaled vehicles, and all that stuff I thought I was getting from 4". If I could only have one, I'd probably still pick 4", but I love the benefits of both the larger and smaller scales too.
I can't recall the last time I even touched a 4" figure. I have somewhere between 3k-4k Joes in bins not ten feet away, and it's been a couple of years since I handled one. The rubbery plastic and fragile feel of 25th Joes made me less interested in them for anything but MOC collecting. Remember when Joes were made of hard plastic, never had bowed legs or other random deformations, and could hold a pose? I do, but they haven't made those since DTC. But the big guys and tiny guys, they bring me great joy seeing them on the shelves and they're actually a pleasure to fiddle with.
Joy Toy looks good, but the prices are absurd. No chance I'll pay $30 for a 4" figure. And they have zero nostalgia at all. If I owned any, they'd just be OpFor or cannon fodder. Rando soldiers just don't blow my skirt up. ¯\_(ツ)_/¯
