I tried both overgrips at exactly the same time, to test them out, bought a 3-pack of each, and tested a Wilson & Yonex on different racquets. I liked both, but for me, Wilson lasts a bit longer, and overall felt better for a longer time. They both get very dirty, but, heck, if I found the overgrip that lasts the longest for me, I couldnt give a crap about having dirty overgrips. They get dirty cause they're white, but then, the white ones are the best ones because they dont have added color on them
