What's the best Halo game?

What do you guys think the best Halo game is. I personally think its Halo: CE. The other games just didn't have the feeling that it did. I hated Halo: 4 for some reason. Just it doesn't seem as fun as shooting aliens on a weapon that could destroy the galaxy.

2 > 1 > 3 > Reach > 4 > ODST

The first three are all ****in stone cold classics, but I think that 3 got the perfect mix somehow. I really like the Warthog run at the end, too. 3 > 1 > 2. I've played 4 and Reach, they were fun, just didn't have quite the same feel as the classic trilogy.

Edit: wrong section of the forum, btw.
