Do you really care about bonus/side stories?
I have re-purchased some of the titles(actually all) I have purchased in the past just to I can read the side stories and get extra content. In fact, I only by the premium version now :) ( and I do agree that Realist is best for the extra stuff.)
I love having the bonus/side stories. Like @raitoiro I haven’t found the recent Grimgar to appealing, but the earlier ones from that series as well as almost any I’ve read from other series have been great.
