E-Flex all the way for me. Ear and chin protection depend largely on how I wear them. They can be positioned so they cover lower a bit better. I tend to do that, because I run a visor (yay, old fart syndrome!), and that gives MUCH better forehead protection.
My E-Flexes are the third set of Vents-lensed goggles here. Picked up Avatars that allowed me to retire my Profilers, then moved to E-Vents, then to E-Flexes this last spring.
