I love these games, but I cannot stand Origins. That game made me strangle seagulls.

2 is also my favorite. 3 is behind it, mostly because of nostalgia. The games aren't exactly wonderful to play. Homecoming is far from perfect, but I consider it a step in the right direction gameplay-wise (but not as far as story goes -- it was kinda horrible). Although behind 2, I think The Room had the second best story. I've only played it once, though. Something about that one screams "Enjoy once only."
