For me...well.....doing as the other...
For gravure:
-Kawasaki yuu ( search her,i even had a post for her...omg that tanned ass );
-Tsunko (very famous cosplayer,but her gravure video is an Holy grail ) ;
-Tanaka rie (for being 41 this seiyuu has an amazing body...i saw her first fb but the new one is hard to find)
Then the usual...but the best for me are the joshi...
For Av is easier to do a list:
-The goddess duo Okita Anri-Hitomi;
-The Gyarus Aika,Shimoruna (the legend Mana Izumi ) and the recent tall gyaru Hana Shibuya and Arisa Seina (her ass again)
but lately my preferred actress is Himekawa Yuuna,esepcially her S-cute works (pixie cut tomboy with an happy and smug face and a very good figure,and she can move well ifkwim )
