I have both the solid and lace bandelettes.  I prefer the solid as they seem to stay in place better and the lace ones have gotten a little torn from use.  I have tried so many hacks for chub rub.  I have creams and deodorant style sticks and none of that works, or it works for an hour and then the rubbing starts.  The bandelettes are awesome because they don't wear off and once they're on you'll forgot they're there.  I wore the solid ones under a skort to the beach because the shorts in the skort are not long enough to keep my thighs from rubbing together and I completely forgot I was wearing them until I got home and had to try to clean the sand off of the silicone strips.  If you have chub run, buy them.
