2 - NeuralDSP
Both of them are above 1000€/$. We are talking about 10x the price of this thing. Add some Multi-FX Pedal (like Line6 HX-Stomp) where you put this in the FX-Loop and you end up with something equally good for still half the price.
And in general, its not about what is better, digital or analog. It's about the use-case. In the studio or when noodling around with the knobs when practicing: Real Amps and Pedals. But on stage, you don't play with the settings of your pedals or you want presets. This is where you go digital. No one will notice the slightly different sound there anyway.
That said, if you use a preset based effects setup like rackmount gear, I could see how this would be cool.
I know some who change their settings during playing, but I wouldn't consider this as standard. Also, you can still add a real Pedal to a MultiFX Board if you really want to change its settings live. On the contrary, automatically changing the settings controlled by your DAW and triggered via MIDI into your MultiFX unit is also pretty common. You don't have to hassle with your Effects at all and can concentrate on playing, what you should, as you need to be absolutely on point.
Given that this was the only really active process on the pi, it ended up working really well. I simply converted modules I had written for vcv rack.
I also built one that enabled usb host mode and acted as an audio device that worked with any daw. Ended up being pretty cool for about $20 of parts.
While not as cool as an ml system, given that I was already writing dsp, it ended up being pretty neat.
another is add more params to the models to take the knob states into the account when doing predictions (which can impact the performance)
