Either choice can work well, depending on how separable the points are, and how “big” they are (including how much text you will devote to them, but also how controversial or interesting you predict they’ll be in spawning further replies and discussion). You can also mix the styles—one comment for multiple simple points, and one with depth on just one major expository direction.
I’d bias toward “one reply” most of the time, and perhaps just skipping some less-important points in order to give sufficient weight to the steelman of the thing you’re responding to.
Another hybrid approach if you have multiple substantive comments is to silo each of them in their own reply to a parent comment you’ve made to serve as an anchor point to / index for your various thoughts. This also has the nice side effect of still allowing separate voting on each of your points as well as (I think) enabling them, when quoting the OP, to potentially each be shown as an optimally-positioned side-comment.
