for textured i have the biqu plate.
its very durable and you can use both sides.. i scraped mine a couple times and its still ok.
the material is bonded to the steel like a powder coating. its rough so makes rough bottom prints.
for smooth i have the creality gold plate.
this one is not very durable as the coating is a sticker.. if you dont let it cool off completely you will peel it off with the part.. its also only coated on one side. it makes super smooth bottom prints tho..
to be fair i use the smooth one the most.
