For me it's Muv Luv, mostly because it was my first big one. I know there's technically better stuff and the third game has a very weak first half. The addition of a second team was unnecessary baggage. But I just can't help loving it as a whole.
My top three would be that, Baldr Sky and Muramasa.
Maitetsu was a surprise sleeper I wasn't expecting to love, it was just so comfy. My only complaint was how the H scenes were separate from the story.
Made it too unnatural, I tried one or two and just couldn't get into them because they had no real connection with what was happening in the story.
