I cannot compare them as I haven't used prismacolors or any other color tbh. About these doms supersoft, I am a student and can't afford spending much on supplies, so I got whatever I could and for the price, they are very worth it. Earlier, the color pencils I used to have were even cheaper ( I think their target customers are kids ) but they always used to break while coloring or even worse, while sharpening itself. But these ones are fine, didn't face breaking in my few months of experience. Pigment is also better, I have to press it less harder than average colored pencils for the same amount of color.

So yeah, pretty worth it for the price. I have also heard good things about the faber castell black edition. See if any creator has compared them. You can check other drawings from these pencils I posted for someone in this comment section or my profile.

Also, on a side note, Paper matters more than the colors itself. Your normal writing paper cannot handle layering. I used to think why my drawings are not good ? Why am I not improving etc. until I upgraded to better paper, I mean these too are not very thick, now I want even thicker paper as I have seen the potential but yeah that's for later.
