I completely agree with you about Vivan and I think he was only 21 years old at that time since he was born n 1962 and this was 1983! His speed, aggression, sense of melody, and vibrato were all so good. It’s sad that he went to Def Leppard. To me anyway. In 1983 that was state of the art playing and as you said still quite impressive.
Regarding Joe Stump being ranked relatively low on Willjay’s list, I’d guess that was because Stump’s fastest playing is all economy picked and those economy picked licks didn’t qualify since the list was for strict alternate picking. I think Stump is good, but damn, I’ve never seen anyone try so hard to be just like Yngwie, right down to using not just the same guitar but even the same strings, all the rings and other jewelry, and now he’s finally achieved his dream - he’s the guitarist for Alcatrazz.
Greg Howe I think probably is slower than Yngwie but Howe is an awesome player. His strongest point is his phrasing which was extremely unique for a Shrapnel signed player. Dallas Perkins, the teacher who taught me for a few months in 1988 when I was living in Tampa and taught me how to sweep pick said Greg Howe was one of his favorites and maybe the best of all the Shrapnel guys because of his phrasing. Howe has as different a style from Yngwie as he could possibly have and still be considered a shred player. Another thing I like about Greg Howe is he endorsed the first serious guitar I ever owned and the guitar I have played more years than any other - The Fender Heavy Metal Strat.
The Fender HM Strat is a truly awesome guitar with its 24 fret neck with a 17 inch radius, the Kahler locking tremolo, the Dimarzio pickups - it’s a Strat in name only! it’s a beautifully made guitar, I love the feel of the neck, and mine has a very nice paint job - it’s a marbled wine colored guitar. It’s gorgeous. I couldn’t find a picture of one so picture one like this but wine colored and the marbling is black. Everything else including the maple fretboard is the same.
