Eventhough DYRL is the most memorable, my most favorite is probably macross zero, because how different it is compared to other macross series.
Not the plot or character, but how do you say it, the atmosphere? more gloomy, and i like it, closer to real war situation i think.
How they explain the protoculture in mystical way, and also the leap in term of animation by using full CG for the first time if i'm not mistaken.
But still, macross is also about love song, so it's either DYRL, plus, or zero.
