I've only been using the Fitbit Charge 4 for three days, but I'm already fed up with the rubber strap that comes with it. Not only does it feel trashy, it doesn't breathe, and the difference in notches means it's either tighter than you wanted or looser than you wanted. The metal braid on this strap is open enough to be moderately breathable. , that's all I need from it. In addition, since the closure is magnetic, the size is almost infinitely adjustable, so you can choose a tight or loose fit depending on your needs. And of course it's all metal, which seems better than the rubber shit they give you. It's definitely a worthwhile upgrade, especially at this price point.
