That was one of my biggest issues with digital - trying to replicate real gear, instead of being something new. It would be like Moog or Buchla developing their synth technology and trying to sound like a grand piano.
when the goal of technology is to replicate, not innovate, the comparisons with real will always be a challenge.
I had an email exchange with a software plugin maker about this, and he said if they didn't have models of real amps, cabs, mics, speakers, etc. no one would buy the plugin. Even now with Helix and Fractal, it's often about the newest models of whatever real gear, and how much realer it sounds to the real thing.
Several years ago, I found Blue Cat Audio's Destructor. Originally it wasn't focused on recreating real gear, but a tool to create (what I called sculpting) a guitar sound. Fast forward, that Destructor tone sculpting tool is still there, but now it includes many presets designed to sound like real gear.
One of the many reasons my favorite guitar plugin is PolyChrome DSP McRocklin Suite is they take the sound sculpting approach, with a logical signal chain. You won't find models of real amps, cabs, speakers, mics, etc., only descriptions of the tone / sound / purpose of the components. It's digital guitar processing that embraces the capabilities of digital rather than trying to mimic recreate analog.
Wish there were more of these plugins (Destructor and PolyChrome DSP are the only one's I've found so far).
IMO
