I haven’t found anything that beats a lounger chair for comfort in use without a tree. Using on a tree, there’s stools and innertube cushions. Then again, I have lumbar plates and screws, disc issues, arthritis, etc….so lots of minimalist stuff just doesn’t work for me. I’ve had most of the seat/framed vests available, and I’d rather my vest/pack/belt NOT be attached to my chair/stool. It’s a PITA to access anything in the rear of a vest/chair combo once seated. I like throwing down my seat, and laying my calls out for access, then just throwing it all back on for the jump. Just me.
I’ve got several gobbler loungers, they’re very comfortable. But I almost never use them for turkey hunting, they are a pita to carry around.
