I agree with this statement.
Every reason is baised, its an
opinion, just because another game has more guns/maps/etc doesnt mean its a
fact that it will be better, its all preference. You dont have to have a reason to explain your preference man.
I enjoyed Left 4 Dead 1 more, I really dont have a reason though, I have both. Probably because I waited months for L4D 1, excited valve was making a zombie game and L4D2 I guess I knew what to expect
