That one is purported to be a hybrid between Horwood and robusta. Mine is supposed to be Horwood.
Here's my original plant and propagates less the one that grew out the center drain hole which broke off and was rooted.

This one receives strong light, which could possibly explain the bleached color look.
I'm not claiming mine is Horwood, just that it's the name represented when I bought it from a Thailand Ebay vendor in 2013.
This is another that features a small rosette in it's immature form, and long elliptical leaves when more mature.
The Chahinian book shows a side view of one with the long leaves, and is not a photo which clearly shows much detail.
In comparing yours with mine, they look similar yet different to me. Curious is that the hybrid doesn't seem to represent characteristics indicative of robusta. I have no idea if that calls into question the purported parent species, or if this is a case where one form (the Horwood look) is clearly dominant over the other. An example I can think of with my hybridizing of aloe, haworthia, and gasteria is several hybrids I have now created involving Gasteria rawlinsonii, whether seed or pollen parent, and hybridized with other gasteria, or aloe clearly feature the basic rawlinsonii form, indicating the dominance of it's characteristics. Regardless of the other parent, the seedlings all look basically much the same with nuanced differences, although sufficiently different enough from rawlinsonii itself to eliminate the possibility that selfing occurred.
How do they look to you in comparison to each other?
there are so many awesome plants around and heaps cheaper!!
