rotor stall in dynamic turn
Well regarding the R44, I would be more concerned because he is dragging the spray boom through the crop. Boss and customer might not be happy about it. It might break of after too much of that. Regarding overpitching, I don't see a problem here. Let's give the pilot credit for his job. He does that day in day out and probably has a lot of experience by now doing this. Crop dusters tend to be very economical with their movements while flying. You can not wrestle a helicopter for hours on end. And in that moment the ship is fairly light and does not need a lot of power.
For the H125, well that looks quite sporty. My biggest concern though is the short line for the bucket. If I remember the Bambi Bucket manuall right, it should be either short enough or long enough for the bucket not hitting the tail rotor. But in that case it looks like the bucket would wrap around the bucket quite nicely. Regarding overpitching, if it is a B3 or later model, I would not worry about it to much. Way more power than you need in this situation. While he does that fancy stuff, the bucket is empty. At least half a ton lighter than full. On the other hand, throwing a helicopter around like that empties the bean jar faster. But he is fast doing it and there is one big advantage in that kind of turn, you can loose altitude much faster. That gives him more clearance over the terrain when he is diving after the drop. Since CFIT is a way more cherished method of bending helicopters than overpitching, I would go with his method if speed is the main concern.

It is difficult to decide if the R44 pilot deliberately sinks into the ground cushion or if he runs out of power making a sporty turn like that using a boot full of power pedal at the same time as he loses translational lift. As rotorbee says, he is taking risks with the hardware strapped to the aircraft that aren't necessary.
The 125 pilot is an accident waiting to happen and presumably knows he is being filmed.
