Mineral B vs carbon steel frying pans

I am looking to buy a frying pan but the material has confused me.

One is said to be Mineral B, the other is carbon steel. I was confused about the differences between the 2 materials. Thankfully, I wasn’t alone and found https://www.chowhound.com/post/confused-de-buyer-mineral-element-pan-iron-steel-greatly-834744 which goes into detail about what materials exist within iron / steel etc

If it helps, the 2 products I’m looking at are https://www.debuyer.com/en/products/carbone-plus-round-frying-pan-stainless-steel-cold-handle and https://www.debuyer.com/en/products/mineral-b-round-fry-pan

What I can’t tell is, if there is going to be any difference when cooking and caring for the 2 frying pans.

I am not asking for a recommendation. I’m only interested in what one could expect to cook using the materials (and if the difference of the material really is going to make a difference)
