Most influential, I think maybe:
Les Paul
Django Reinhardt
Jimi Hendrix
Muddy Waters
Tony Iommi / Keith Richards
Les Paul was the most influential guitar player of the 20th century. Hands down. He invented the electric guitar so none of these other guys would have amounted to anything if Les Paul hadn’t paved the way.
On acoustic guitar, Chet Atkins was the most influential guitar player since the guitar was invented.
Good list. For influence and most current popular guitar driven music Iommi has to be included for sure.
