I would say that 80% of my shots are standing.
I'm absolutely on board with the advantage a solid platform gives when executing an archery shot. I just setup differently than you, so maybe that's why a hybrid system is working better for me than it did in your experience.
I've shot most of my bucks standing as well. (had to kneel twice to avoid limb interference).
Given a tree that will accommodate any direction of setup, I don't personally differentiate how I go about it from a hang-on stand to a hybrid setup or to a saddle + platform.
I know I will very likely be standing for my shot and like you, I prefer to be.
So, even in a standard hang-on set, I want to be positioned so that if I have to stand from a sitting position, I have a little cover. This means setting up so the tree is between me and my most likely shot opportunity as much as possible, but offset from 180 degrees to that potential shot enough to have space to manage the shot.
With my hybrid setup it's the same, but the advantage is I mostly sit in the saddle when I'm not on my feet, so I'm facing that direction more of the time and it's an easier and less visible (to the deer) transition to a standing position when a deer comes in as expected. You do have to be a bit conscious of your rope situation though when a deer comes in from certain sectors outside of the defined pattern you set up for.
I manage my saddle platform the same way. I use big platforms that afford standing shots. (Ridge Runner XL, LWCG Fix)
Now, if I wanted to shoot from a seated position to an area of defined movement, then I'd be facing that sector more.
Anyway, that's how I look at it, personally.
