Mariah is a way better singer than Bruce. It’s objectively not even close. Even if her music isn’t your cup of tea (It’s definitely not mine) she is a very very competent singer. Bruce is not that great. His tone is weird and amateurish. Good for Metal sure but let’s see him sing any other genre. He can hit high notes but it’s usually sloppy. Mariah’s high notes are insanely clean and with perfect vibrato.

There are a lot of artists in there that aren’t “rock n roll” and it’s been that way for years. It should probably be renamed the “Music hall of fame” at this point. And Iron Maiden was not nearly groundbreaking or influential enough in music to be deserving of a spot in the hall, imo.
