What I most appreciate about Haiku is that it presents other ways of interacting with a computer and doing things. These ways so happens to be attuned to my work flow for getting things done.
As an user, I have to accept that enjoying and productively using Haiku means leaving some of the stuff from Android, iOS/MacOS, and Windows behind.
Projects like porting LibreOffice to Haiku and replicating features from other operating systems like HiQDock are important and worthwhile. However, their existence is not what brings me to Haiku. It is a promise of a better way to create and manage content than via drives, files, and folders.
