I will say that, my journey with HX started with Helix Floor, and then continued with Stomp XL, so scribble strips to non-scribble strips and, FOR THE EXISTING SWITCHING, there wasn't any adjustment period. (Note: plenty of people use the Helix LT without scribble strips).
We are all different, etc, BUT, the Stomps DO give you a layout to see what you are doing, it's just not scribble strips, and like previously said, that's what the different colors on the footswitches are for.
As you said, if you add long press and double tap, maybe then it gets a little more scary, but I'd personally rather have an HX Stomp XL, especially to fit onto a pedalboard, or to carry by itself, (mine fits in a mono tick bag with a mission expression pedal and other cables/accessories), that is also a backup piece to whatever else you are using, because it has the modeling :)
