Chameleon is a stiff line with little stretch, as mono goes anyway . Chameleon is a better line for jigging, plug pulling, trolling, downriggers etc. and it might be just a hair stronger than UG. BUT it is Too stiff in my opinion for drift fishing. UG is a softer line that is much easier to cast and it has excellent knot strength when tied properly. I think both have very good abrasion resistance and low visibility.

Neither one of them is suitable for spinning in my opinion.
