personnaly, on my 20 regulars or ex regulars players, most of them prefer Imperial or Bauhaus, and very few Capitol.
But, I've started an open Capitolian table since 2 years, and players changed their point of view.
Capitol is profit, opportunities, liberties and a very different game style. I've developped new units, incorporated WZ back ground, developped political, structural and economical aspects ( like banks, stock exchanges, directories, directors, political campaigns ) for an true Dallas like dynastic campaign, or CAPITOL RANGERS like old Texas ones with our friend "Chucky" Norris

or else PSS for an amazing campaign between batman, men in black, X files, 24H or NCIS ( i've always loved cross over style :p )
IMHO, after 10 years of GM experience, Capitol is one of the most playable corp, and indeed, the most valuable to GM about games opportunities and devlopments, even my favorite one's is Bauhaus
