The Netherlands has actually way more choice in parties to vote for than just two or three. Smaller parties have pretty decent power to influence policy, as long as they get enough votes for a single seat. The difference between zero (no voice) and one seat is much more important than the difference between one, two or three seats.
And even the larger parties are not at all identical, especially when compared to the US' Democrats vs Republicans (although I am aware that this is in the US largely due to the "gridlock" mentioned in the article). Also, even the larger traditional right-wing party VVD is relatively left-wing when compared to US politics--they even consider themselves "liberals", to the point that the word itself is often associated with right-wing politics (the previous chairwoman Femke Halsema of our Green Party sometimes explicitly referred to herself as "liberal", to mess with this preconception, and try and reclaim the term).
