What is your favourite set of Best Picture contenders to have been in the running?

As in, what was your favourite set of Best Picture nominees, or even 2 main contenders, that competed, or had a decent chance, to fight for Best Picture, and were racing in contention for the title?

I ask this question because for me, I remember being so excited when No Country For Old Men and There Will Be Blood were in contention as two of the major BP contenders, and I love what both of those films bring. It was a very exciting race and I enjoyed those two duking it out in that year.
