You don't need it if you print slowly, and you don't need it for reliable old PLA. If I squint, I think I can see a difference, but it's marginal. Thing is, the X1C isn't really for printing PLA. If you only want to do that, you'd get a V400 or a Voron. When I print PC Blend, though, it's... the difference is glaring. This isn't something that needs a lot of testing; with the lidar off, the corners look like semicircles. Also monotonic top/bottom layers don't fill the full surface, because they have corners on both ends. About like you'd expect, and the difference isn't visible from the outside; external perimeters are always printed slowly anyway.
