I didn't read any of the other lists yet because I wanted to give mine before I did. So here we go.
5. Eddie Van Halen- Most would rate him higher.
4. Richie Sambora- More gifted than most realize.
3. Steve Vai- His early work with Roth is classic.
2. George Lynch- Put him in another band (besides Dokken) and he would be legendary.
1. Jimi Hendrix- No one else compares.
Goof, you are the first to include Eddie. My opinion is he's overrated, but I'm also surprised it took this long for him to be mentioned. The rest of your list, I like a lot. Richie Sambora is a really good call.
