Hardie board vs Nichiha?
Answers:
I also use hardie backer, but only where I have uniformly spaced studs to nail to. I did a tile shower installation in an older home where the studs in the wet wall were more than 24" apart, and I got significant flex in the hardie backer. I was using 8" tiles, so it firmed up, but I wish I had used durock or something more rigid.

On an 1892 house, I would go with Nichiha as it's smooth lap & shake products are 1/2" thick vs. Hardie's 5/16" thick products which results in a much deeper shadow line and results in less breakage. The Nichiha product is also an 80/20 portland cement/wood chip base rather than Hardie's 70/30 portland cement "pulp fibre" base. Hardie products are also "layered" reather than pressed from 2 pieces under high heated pressure like Nichiha resulting in a smaller chance of delamination.
Hope this helps,
