I played Reach more than any of the others and I really enjoyed the customizable aspect of it. Played the campaign and the multiplayer endlessly with my friend.
Halo 3 was the first Halo I ever played and I really enjoyed playing it with my friend via splitscreen, but I never bothered with the MP as I did not have broadband when it was released.
Halo 4 was great visually, but I stopped playing the MP a lot earlier than I did Reach and I never finished the campaign.
I bought Halo Anniversary and tried to play Halo 1, but I thought it was incredibly boring and devoid of any excitement or life, so I stopped playing 3/4 into the campaign.
I've never played 2, ODST, and 5, so I'm not commenting on those.
