On the secondary weapons I'm used to games like Raptor where they actually add into your "my perpetual spam of death setup", and I enjoy that more than the thing I sometimes use for a different effect, but can hardly spam because my energy is all gone.
That said, some of them I've really liked, like the hunter killer and the nova.
And I haven't really been playing from the perspective of "this run matters to me at all", just testing stuff. So the main guns feel more than sufficient for most of that.
