Real smooth scrolling where its actually tied to the movement of your finger is very good. Fake smooth scrolling where it's trying to interpolate between scroll events is shit.
I don't know why desktop mice are still stuck in this 80s era of jittery scrolling while trackpads and phones have been scrolling with pixel perfect accuracy for over a decade. And now every product page is tying animations to scroll position which looks great on smooth scroll devices but play as 1fps animations for mice users.
My mouse scroll wheel isn't "smooth" so it makes no sense for it to be smooth for me.

This is definitely something needs to get used to. But the biggest advantage of non-smooth scrolling is that it starts and stops instantly with zero overshoot, which is what I hate of smooth scrolling.
To be more clear, I actually use all three types of scrolling, for different scenarios.
I manually drag scroll bar for finer control, and it has no suden jump issue. I also use auto-scroll (middle click) for super quick scrolling (which is kinda like smooth scrolling).
If you use a trackpad or touchscreen and keep your fingers on, there is no overshoot. This only happens if you move and lift to give it some momentum, or fake JS smooth scrolling.
Yeah, I have no problem using "smooth scrolling" when using fingers or touchpad (is there even non-smooth scrolling for these types of inputs?); they pretty much act like dragging scroll bar using your cursor.
