It might seem a bit complicated if you’re only used to 5e, because core mechanics like conditions work rather differently in Pathfinder, but it’s honestly much more flexible than 5e’s system. Rather than having an abstract number of passes and fails, you have a single number that fluctuates up and down. Less things to keep track of.
You do have the wounded condition on top of that, but it helps counter the thing you see in 5e where people pop up and down repeatedly with no consequences for repeatedly being beaten unconscious.
