That depends on what you mean by "pretty much the same."  (There was an
argument on Usenet about 20-ish years ago over exactly this term
regarding pointers vs. arrays in C.  I commented that I once blew a job
interview for tacitly considering them "pretty much the same.")  I'm
amused that you're saying this on a thread by the same person who
schooled us on the difference between points and vectors.

The difference between L and V actually changes the meaning of
saturation between HSL and HSV.  Michael Horvath gives a pretty good
visualization here:
