2) I feel like "easier to play" and "faster/tighter response" is the same thing. I'd rather be able to play tight without a tubescreamer and a noise gate which I'm confident enough to say I'm capable of doing. Not being a douche... I sure recommend the TS+NS trick to guitar players who profit from the effect.
What you're saying makes it sound like you think you are too skilled of a guitar player to need a tubescreamer to get that kind of effect,. You act like it's some crutch for poor guitar players, and that is absolutely ridiculous. If anything, I'd say it's the other way around... It benefits SKILLED players. It's much easier to hear when there are timing mistakes when the signal is crisp/clean/clear/quick and notes aren't blurring together due to a saggy/mushy/undefined guitar tone.
Tubescreamers and noise gates do not pick for you. They don't control your timing. They don't control how precise your picking is or how intricate your playing is. You will NEVER get the same quick/tight response without using a tubescreamer or overdrive/EQ pedal of some sort before the amp, no matter how good your rhythm timing is. It's not about your timing. It's about the response of the signal coming out of your cab. It just gives you a more immediate, percussive sound. It's a stylistic choice, not a crutch.
Well if I hear: "I'm using a TS to boost my 5150 into a Recto cab", I'm sure as hell not thinking: "Wow, that's original!". Ofcourse we all have heard a tone somewhere that we liked and want to replicate that. That happens to all of us guitarists. I don't think a tone as generic as that will stand out in a song anymore since it's been heard over and over again for at least ten years.
This is just my philosophy on the matter and you don't have to agree with me but all "great" guitarists in the history of music have a tone of their own. Jimi Hendrix, Slash, Steve Vai, Joe Satriani, Mark Knopfler, John Petrucci, Tom Morello etc. They all sound different and somewhat came up with their own sound to make them stand out. I'd love to see guitarists coming up with their own sounds whether or not it's a boosted sound or not.
I think you once again missed the point. I said I'd rather stand out with interesting, original music & playing/phrasing while using a guitar tone that I like, no matter how similar it may be to other modern metal albums, rather than trying to have an "original guitar tone" just for the sake of being different... If somebody ignores original music & phrasing just because they find the tools used to produce the tone to be a generic combination, no matter how well tracked/mixed/produced the playing is & how good the guitar tone sounds, then I feel bad for them.
Also, I've gotta say, although they are all great guitarists, I think most of the players you just listed have never had would I would call an amazing sounding guitar tone. They are known for their songwriting & overall playing style/ability, not their guitar tones. Even Petrucci, sure he's often had a great liquidy smooth lead tone, but the rhythm tone on most of his albums is so weak and messy... and it sure isn't because of his timing...
Personally, I couldn't care less whether you like using tubescreamers or not. You just say some highly inaccurate, ridiculous shit that deserves to be addressed...
