I agree with you. I also don’t use all “standard” KDE applications, I prefer others like LibreOffice (I was also surprised that in the review KOffice is and not Calligra.), Firefox, Thunderbid and many more. The KOrganizer you mentioned or KMail are inapplicable for me.
However, the review is primarily focused on finding the best distribution with KDE.
