Like slay said, Angelo is the speed king and funny to watch when he does his hand tricks and play´s on two necks. Also when he skipps from neck to neck at high speed is truly amazing.

Petrucci is probably best. He´s got evrything, speed, felling and amazing creativity.

Zakk is my huge fav. He´s playn´is great and his posing is better than Slash´s. King of the Screamin´ notes.

Gilbert is also one of my fav. and a big influence. It was thax to him I got into string skipping stuff. Fast as hell especially during Racer X era and is pretty much of an alarounded guitarist now. Play´s evrything from pop to metal.

Becker is the king of sweeping and one of world´s most talanted players. When you think that he was only like 17-21 yrs. old while he did all those amaznig things...well. I feel very very very sorry for him ´cause of his ilness. He had so much more to give but yet he gave us A LOT. Get well soon my man!!!

Dime is prince of riffs (James Hetfield is the king). He´s a cool player and I have to disagree with Sly ´cause Dime has amazing technique. Can play very fast when he want´s and he does it often. Has amazing bar technique. Negative thing about him would be some off horrible solos he done when nothing makes sence but still, it´s orginal. Also main melody of Hollow is a masterpiece.

Bucket, much more techniqual than Slash. Can produce some amazing sound out of his guitar and is at Angelos level of speed. But compared to Angelo, Bucket have much more felling in his playn´. ´His solo work is pshyco.

Of these named players you should definitly check out the following ones:

JOHN PETRUCCI (DREAM THEATER)
ZAKK WYLDE (OZZY/BLACK LABEL SOCIETY)
PAUL GILBERT (RACER X/MR. BIG)
JASON BECKER (CACOPHANY/SOLO STUFF)
