I don’t know Joe Stump well enough to say since I just a heard a few things by him and didn’t like it and moved on. No doubt Yngwie and other early guys deserve props for starting it, but that’s independent from who’s actually the best player. As for Becker, by modern standards I maintain that he’s sloppy, but brilliant for his time. It’s not his excitement, it’s more actual technical issues, but they’re not at all unique to just him. Even a lot of modern players have some of the same issues. Consistently he rushes a lot the downward part of his 5 string sweep patterns (making the note spacing uneven) with many of the inner notes being glossed over (not clean). Slow it down on YouTube when listening and you will hear it. This comes from a lack of control in technique. Some of these very clean modern players wouldn’t have that issues even if they were very nervous. They just have higher level baseline technique as we can expect with successive generations of players. Not saying I prefer them (I don’t), but for pure technique there’s no question
