SRV never even approached the greatness of Jimi in either in innovation or just flat-out blues jamming ability.
Depends on the time period. Hendrix had to work in show bands like the Isleys and King Curtis, which SRV never had to do. A lot of work went into public performance and he had to play a multitude of styles.
Take a listen to some of the waltz and fast blues that SRV played like "rude mood", "say what" and "scuttle buttin". Then get back to me.
His chord progressions we're very unique. You can't tell me that any blues player had switched between A minor to E minor stuff like that. Timing, cleanlines, picking, speed, accuracy, amd chord blend were fantastic.
Nothing quite like that texas blues sound.
