I'm not going to comment on tone at all - obviously so subjective. But the sentence and a half above perfectly sums up what many tube amp users see as significant factors outside of sound.
My personal take on digital 'solutions' is pretty simple - I don't have fun, it doesn't feel inspiring, and I have never had a 'memorable moment' using one. For many users, I just don't think the technology lends itself to uniqueness, happy accidents, rebellious envelope-pushing, or good times in general really. The uniqueness part is counter-intuitive really. Surely with limitless options digital enables there would be an amazing array of new and original tones out in the world?
Anyone who has had, or regularly gets that rush from a killer amp/cab combination knows the feeling well. You dial in the amp, hit two chords and it just feels great. You end up playing for ages, get inspired, and wish to God your bandmates (or spouse) could understand the importance of your mission.
What is completely irrelevant to this type of player (and I'm one), is say a youtube video demonstrating that a Kemper profile recording sounds very similar to the real amp. Or that your buddy has a Fractal and swears he can't hear a difference. Or a forum dude saying amp guys are dinosaurs etc.
If everyone I knew told me synthetic beef was awesome, cheaper, more convenient and they couldn't tell the difference then I'd probably try it. If I didn't enjoy the experience after a dozen attempts, I'd just stick to a known entity that I do enjoy. And that's how you end up with a wall of amps, and a freezer full of Wagyu.
In 50 years I wonder if anyone's list of '100 greatest guitar tones of the last 100 years' will feature many entries outside of tube amps? Now that would be an interesting glimpse into our tone future.
