Who is your favorite rock vocalist?

Serj Tankian has to be my favorite. Lonely Day came on a mix of mine on Spotify, and I hadn’t listened to any System of a Down in some time. I think out of all rock vocalists I have listened to, admittedly not enough, Serj has some of the most unique vocals or vocal runs in songs. It’s so satisfying to listen to. What are your thoughts? Who’s vocals consistently give you that stank face or just make you close your eyes like, “Damn, this is beautiful,”?

Edit: Just learning Lonely Day is actually the guitarist’s vocals with Serj doing backing vocals on the track. My answer still stands but boy do I feel silly.
