Actually, your thread was 'Who likes Santana (damn near everyone!) AND "what do u like?" which was an open invite to list our OWN favorites.
Actually, I only plink at guitar, but worked for more than a few years as a professional pianist/organist/keyboardist, so I admire a wide range of genres.
But, as usual, when it comes to guitarists, people tend to overlook the country genre. There are some incredible finger pluckers that came straight out of Nashville.
Just to name two of the greats, and you might scoff, but if you check around, you'll find that the guitar greats of many higher profile genres also give kudos to these two...
Glen Campbell, and Roy Clark (yes, of "hee-haw' fame!). They are two virtuosoes, imho...not that I necessarily liked much of their commercial hits. But their mastery of their instrument was complete.
For classical, I am partial to Segovia
Classic rock, try Alvin Lee, of 10 Years After fame.
Folk Rock, I could listen to James Taylor pick and grin (or frown) all day long
I also like Stephen Stills, (better than Neil Young, purely as a guitarist)
For Alternative rock, I tip my hat to the late, great Frank Zappa.
