I used Hardibacker for our showers. It's thinner and easier to cut.

The backerboard is a minimal cost compared to the rest of a tiling
project.

Do it once, do it right.

Do it once, do it right. Use Kerdi (Shluter system)
Either standard Kerdi over whatever wallboard you want to use, or
KerdiBoard. You don't need soncrete backer with Kerdi, and you use
thinset - it is totally waterproof and pretty well goofproof. It is
not particularly cheap, but good seldom is. It has a handy "grid" for
helping to keep the tile-job square. They also have KerdiDrain for the
bottom of the shower (pan) to use with Ditra to make a waterproof
shower pan.

Agreed! We used the standard Kerdi for our showers:

I had not heard of Kerdiboard. It looks interesting but wasn't available
when we built out house in 2003.
