First and foremost,
Stranger is a social satire that takes great joy in turning sacred cows into hamburger. On another level, it's an allegory about individualism.
Troopers is a political allegory about communism vs. capitalism. The government of the Federation is more in line with a Randian libertarian minarchy than any flavor of 'fascism'.
The two books were written for completely different reasons and to achieve completely different ends.
I love 'em both.
