Areas where AM4 utterly destroys Stomp -- like, just obliterates it. And I like Helix, but:
(1). reverbs. All of them. Honestly, a VP4 is almost worth its price as a reverb pedal.
(2). rotary. Helix rotary options are all abysmal.
Other effects I can see some people getting nitpicks about one over the other, but man, the reverbs in Fractal are just SOOOOOOO good and extensive, and the rotary effects in Helix are just SOOOOOO bad that there's no comparison.
If you're trying to use these devices as something kind of like "a UA amp pedal, but with lots of options instead of just one amp" and the UA Dream is one you want to be able to cover the AM4 kills because its spring reverb and tremolos are SO. GOOD. And amp channels let's you cover variety of black panel, tweed and/or brown panel all in one preset:
block 1 drive; block 2 spring reverb; block 3 tremolo; block 4 amp.
Enigmatic for your Dumble goodness in one preset -- you've got enough room to add in your fave Robben Ford slap delay to make it realer.
Lion: For straight Hendrix fun you can do Fuzz, Wah, Vibe, Amp. Or Fuzz,
No but in most cases it still exceeds what the competition does and it has use cases
You can have a fender deluxe and a Klon
Or a Plexi/ Screamer or An Archon/ horizon drive
I don’t see anything there that I would call misleading if people do a bit of research (not you) into what they are buying there would be no surprised
Fractal is also the only one and I know of that can do this
With channels even with the entry AM4
There is nothing disengenious there in my option it works as advertised
(1) with delays/cerbs/etc. trails are very different with channels than with “4 delays”
(2) given the limited nature of the foot switch configuration and there only being 4 scenes - the idea you propose is effectively like setting up different presets with those amp/drive combinations.
There are times when Stomp wins (if you want a delay or verb both in front of and after the amp in one patch).
