I have the NR Adventure size cover for my 2018 650XT with topcase and side panniers. It fits well. I cannot comment on the other sizes you mentioned as I have not had any experience with them. But the ADV covers all plastic, front and read fenders, side cases and foot pegs. The quality seems fine but I have only had it for a couple of months, so no real testimonial to longevity.
Hope that helps!
