I can't compare these to any other compression leggings, because they're the first I've tried. But I can certainly compare them to not wearing compression leggings, and these feel great!
Though they looked awfully small, the fit was actually great, but the small end was very tight going over my ankle. Hope I don't break the stitching pulling them on & off. Looking forward to wearing them during and/or after 100 miles next Sunday.
