Cattle Decapitation still plays in E I believe. The old death metal band Insanity did as well, as did Opeth until the last album. Can't think of many other death metal bands off the top of my head though. Not contemporary ones, anyway.
But yeah, standard tuning has definitely been bigger in black metal. Emperor kept to it until Prometheus, and Darkthrone only started tuning down on the last few records. Actually, pretty much any older black metal record considered a classic is probably in E.
Katatonia's first record is in standard as well, which has been pretty unusual in doom for a while now.
