When I lived in TN and hunted WMAs and farms, I used a vest. I’m not sure if I put much thought into it or not because that’s just what you do when you turkey hunt in the East. It does have the advantage of organization. Biggest disadvantages are that is does not carry weight well and it is hot -too hot for serious hiking.
Since moving out West where turkey hunting involves climbing a few thousand feet and being out in the mountains and backcountry where I carry full rain gear, insulation layers etc, a vest in no way makes sense. I carry a pack with calls in the hip pouches and an inflatable butt pad. Actually heading out I. A few hours to bivy out overnight.
I like to be safe and wear my hunters orange vest.
