I think the main advancement and attraction of the TMR technology over Hall Effect is the better battery power usage. I wasn't aware that it is even more sensitive to movements and changes than Hall Effect, according to the linked article. But don't know how much the differences in battery usage and sensitivity are.

I own a dualsense. I've always loved its trackpad for mouse cursor control in games that are less controller friendly on PC, but ever since the steam deck and it's split trackpads, I'll never look back. The split pads are such a superior option, especially with the way they work with the steam deck's on screen keyboard, or for aiming in FPS games.
