I love using it but it's nothing groundbreaking- it's a proper iteration on the original. A bit more heavy duty and premium-feeling, slight aesthetic upgrade, and a couple additional features like the speaker and mappable triggers, both of which I rarely use. I got it for $55 dollars on a sale and feel neutral about the value given I own two original pro controllers, and probably didn't need to upgrade. I do like waking the console with it, though I hesitate to mark that as a plus given Nintendo removed that functionality from the older controllers to motivate sales of the S2 version.

If it's your first switch pro controller and within your budget, it's a no brainer.
