I used to have Prisma markers, but because they are extremely expensive, I got these. I do have to say these markers definitely are a good replacement to Prismas.
Some colors do tend to bleed a little more than others but if color carefully, you'll be fine.
I'm not sure the life expectancy of the markers though, had these since Feburary 2020 and one already dried out, but customer service was great, answered me quickly and did a great job sending out a replacement.
Overall i would definitely recommend these.
