I always like Steve Miller, just cuz a few of my friends thought I sounded like him back in the day (I'm not sayin, I'm just saying). In his early daze, he could have a powerful, bluesy voice, and then slip into that velvety Como voice he donned so often.

For pure gutteral power, I like Sammy Hagar (yer not just now makin the connection are you?) - he could do the heavy metal screetch, he could sing in a ballsy rock voice, he could show some control on the poppier stuff, and he had good range. Micheal Anthony said he lost a testicle trying to sing backup for him.

John Wetton had a unique tone, but also a lot of control and range. He went from interpreting Robert Fripp's wierdo lyrics in King Crimson, to singing pop prog in groups like UK and Asia. When you listen to listen to a whistful song like Book Of Saturdays from KC's Larks Tongues In Aspic ('73), where he sound's older than his years, to Heat Of The Moment w/ Asia ('82), where sounds like a young man belting a modern pop tune (of his day) you begin to appreciate that this guy, while not ever sounding impressive, always got the job done. He's one helluva bass player too, or Fripp woulda never messed with him.
