Everybody is different; there's pros; there's cons.
First, I really wanted an early tree lounge over twenty years ago. I had one big problem. Up in the air, you had to use a knee to pivot 180 degrees. If I didn't have old knee injuries I would have had a tree lounge.
The openshot is only 15 lbs, so there is no good reason to leave it in the woods. A plus in my mind.
I personally don't like stands without front or guard bars. Thinking about deer and standing on a open "diving board" never appealed to me. For some it's no bother.
Of course, I learned to use a 42 inch bow, a to a, successfully, with a front bar, so my opinion is different.
For my older back, I need something not available on the openshot. A nice cushioned back support.
Every stand has plus and minuses. And there are pluses and minuses for some and not others.
