Oury's are great till they start decomposing. They are very thick. ESIs look like you can get them in Chunky or Extra Chunky. Never tried them but some people seem to love.

Ergon's are the velcro orthopedic shoes of grips. Not very sexy but comfortable. They aren't particularly sticky or cushiony, the shape just spreads pressure over a wider area. Used them for a bit when I was having some wrist issues but they really are ugly and perhaps a sign of a bad fit.
