There hardly are undebatable facts when people discuss campaigns. This is not the first time I see people claiming that Derelict and Transcend aren't "THE campaigns". I'd like to mention the fact that Age of Aquarius has also been criticized.
More in general, a politically correct person wouldn't say that
character-driven campaigns are the best. There are players who prefer pure military experiences, like the ones seen in PI, and their different opinions are to be respected. When people suggest a newcomer to play a CDC, the newcomer needs to be warned about the characteristics of that genre. Please note that most newcomers played the main campaigns, only, so guessing that those players would also like CDCs is not a direct consequence.
Also, it's quite funny how people complain about SGWP2 even if they don't have half the FREDding skills of that campaign's designer. That kind of disrespect towards a person who spent time working on a campaign really bugs me.
