Quality vs quantity is an interesting argument to be had for both N64/PS1/Saturn and Xbox vs Dreamcast.
The N64 and Dreamcast don't have that many games compared to their competitors, but pack a lot of greatness into a relatively small library.
Xbox, thanks to its longer life, had more software overall than the Dreamcast, but for some the candle that burns brighter for a shorter span of time is more impressive than the one that burns longer but less intensely.
