Justified text is really only necessary for multi-column pages where the right margin of the first column looks better if it is lined up vertical against the left margin of the second column. Other than that, justification is a joke.
different users, different preferences - I spent some time googling the topic when I made the earlier post - readability studies were inconclusive; I think that the majority preferred fully justified ( I know I do) as that is what paperbacks use.
anyway it is easy to change the stylesheet to suit your tastes. and current versions of calibre can remove all the extra css crap via an epub to epub conversion
