I gotta say I disagree. I have a red 300, a Tobacco SB JTV59, and a Shoreline Gold JTV69S, my favorites are the JTV's hands down, both from aesthetic and from instrument quality standpoints. I do go for the Fender & Gibby looks, and these JTV's are closer to my norm than the 300 was.
The 59's shape is kind of an LP with a higher upper bout like a Tele... The headstock of any of the 300, 59, or 69 never proved to be difficult for me to be comfortable with, and I have a Strat, a Tele, and an LP as well.
Sometime if/when I get the time, I'll probably either work on the 300 to improve its sustain, or try a tele transplant with it. I don't hate the 300/500/700 body shape, but am just more pleased with the 59/69 JTV body styles. The build quality of my 59/69 JTV's is head & shoulders above my 300, but realize I was going for the bottom (least expensive) model of the 1st gen Variax'es just to see what the modeling guitar concept was all about. Also, the 700 or whatever the top model of the 1st gen Vax's were also in the $1500 range, as I recall. I would hope (and am pretty sure) that the build quality of those models was substantially above my 300...
I use the mag pickups probably 80 - 90% of the time, and the models for certain songs where the tuning capabilities and special instruments (acoustics, banjo, etc.) are key. I think everyone has their own comfort zone and reasons why this is or isn't the route to go. Whatever "it" is, you have to find the "it" that floats your boat... It's all in the eye (and ear) of the beholder. There's a lot of guitars out there that make me shudder, while someone else would go "THAT'S THE ONE!"
My 2 cents.
