In that case, I'd have to pick the Majjhima Nikaya. It has most of the suttas I refer to regularly for practice and contemplation: the Sabbasava Sutta (MN 2), the Sammaditthi Sutta (MN 9), and the Satipatthana Sutta (MN 10) just to name a few. But there are some great teachings in the other nikayas as well. I especially appreciate the Sigalovada Sutta (DN 31) for lay instructions, and the Maha-parinibbana Sutta (DN 16) is very moving and inspiring.
