Bands similar to Judas Priest?

Hi! I properly got into heavy metal with Judas Priest at some point last year, and I've obsessively listened to most of their catalog at this point. I'm also a singer, so I like to be able to sing the songs of the bands I listen to (I can already do so with Judas Priest, except for some of the screams which I'm working on). What bands are there that sound similar to Judas Priest, including having mostly clean vocals with a wide range of notes like how they do?

P.S. I know about Iron Maiden already, though as a baritone I struggle to sing some of their stuff, and I'm already planning on listening to them more (only fully listened to the Fear of the Dark album, and a few other songs here and there).
