Difference between ALC and Ceramic siding which is best?

Hi Konichiwa!

I am iving in Yokohama and currently planning to build a house. Currently it is in planning stage, the housebuilder had given two options to choose whether to go with ALC or Ceramic Siding for exterior wall.

We are very much confused which one to choose .

Can someone explain to understand about the pros and cons of ALC and Siding?

Thanks in advance.
