I like some of the EA7 guitars. Selection of good presets is limited. You can edit them and "make your own". I like the Korg guitars a lot. Yamaha guitars are probably best because of all the presets they make for you.
Ketron guitars are very good too.
Organs...in my opinion the BK9 was much the best. EA7 also very good. Korgs are good. I don't use them all that much so not a huge deal to me. I don't like that the Yamaha preset organ sounds, other than the drawbars, don't do the leslie on/off correctly.
