I haven't skied the '20-21 Prodigy 1.0 so it's hard to say for sure. I've seen some places saying the core has changed, I believe that the factory has changed since the original version but the shape/profile are as far as I can tell, identical.
The last model I tried ('19-20, pink) felt the same as the model from the Roofbox review. I don't remember when the factory switch happened. The 1.0s are definitely butterable because they have tons of rocker, but they're not a ski where it requires 0 effort and no speed, like the Vishnu Wet or Line Blend or something. I really like them for higher-speed buttering though...
They aren't 'stiff' but they are stiffer than many park skis (or at least were in the '19-20 model). The rocker means they can feel 'soft' on landings (i.e. you wheelie a bit) but that's the profile, not the flex of the ski. They're lightweight and the swingweight is minimal, which for me are great characteristics for a rail ski, but I don't think of them as poppy. They aren't dead feeling either, but I would have them as roughly average, balanced between dampness and pop, maybe erring on the damper side.
But what is meant by 'pop' is pretty subjective. I guess when I really think about it now, there are two kinds of pop and they don't necessarily go hand in hand. I generally tend to think of pop as how much energy a ski has when ollieing over stuff, how much spring the noses give you out of butters etc. So a ski like the Vishnu Wet is about as poppy as it gets in that regard. But pop can also mean how much rebound you get off a lip/out of a turn. And in that case, the Wet, for example, lacks much camber and therefore isn't particularly poppy when taking off from the center of the ski. Conversely, the Line Wallisch Pro, is fairly stiff with much less rocker, so it's harder to load up the nose and the tails, so I can't ollie nearly as high. But the camber and energy of the ski in the central section means it feels super poppy off lips and stuff.
The Prodigy 1.0 has a fair amount of rocker, so you can load up the tails/noses pretty well, but the core doesn't have a super 'springy' feel so there isn't a ton of energy when exiting butters. That is what I meant by damp in the roofbox, and it's a positive attribute in mixed snow, etc because it doesn't deflect as much. But they have a decent bit of camber underfoot, so they do have some pop off jumps/lips. This is very much gear nerding to the tiniest detail but that's sort of how I see it.
