I've gone through several sorts of picks to try and find a pick that would fit my needs and I've always come back to the Fender medium as my go-to pick.
The cellulose material really sticks to the fingers, and unlike some other nylon picks, doesn't make my fingers sweat. I find the thickness to be just about right, you can grip the pick tightly and pluck single notes like some other thicker picks, really dig in, or loosen up and strum but without the flapping sound present in some of the thinner picks. I also like the color of the pick, though you might find yourself looking for them if you have white furniture around your house, they blend quite easily.
In conclusion, I'm happy with my purchase.
