For me it’s Tim Pratt, Greg van Eekhout, Garth Nix, Amal El-Motar, Rachel Swirsky, Holly Black, and Vylar Kaftan (and probably several I am missing – this list keeps getting longer the more I think about it).
Though to be fully honest, I also get very excited when I see a name I’ve never heard before (epically if it’s one I’ve never read before). I love knowing I could be finding out about a whole new set of stories to read, a whole new author to explore.
