I don't think it's as "advanced" as "pretentious" these days. We're not producing Black Albums anymore.
To me, a good guitar tone is one that is raw from the source with maybe a hint of EQ and compression. But distorted guitars also tend to take processing so bad and are so easy to mess up unless you really know what you're doing.
It's also easy to focus all your time and energy on guitar tones only, and forget that drums and bass in particular can make or break your guitar tone as easily.
Even if I'm a guitarist and I like mixes that are guitar-centric, guitars are only a part of the puzzle.
