Are G303 and G502 comfortable for palm grip / high sense user?

i'm a deathadder user and tried out the g502 in the past. overall the mouse has a good shape with good button locations and was easy to use. i ended up returning it and getting another deathadder though because it was just a bit too narrow for my liking and i was not a fan of the scroll wheel. otherwise it was great.

not sure if it uses the exact same switches or not, but do know they are the same brand.
