Better late than never. Here's my answer for this awesome thread:
I like both Bangel and Spuffy quite a lot. But, I think that I’ll always see them as two different fairytales, I just like much more the Spuffy one.
Bangel is the first love, the romantic idea of falling in love with someone who is older, protective, tender, mysterious, handsome, a warrior of justice, etc. It’s sweet and painful because there are huge obstacles, but they love each other despite that. It’s the type of love that you wish to find when you’re a teenager. Innocent, magical and intense.
Spuffy is a different fairytale. It’s the story of the bad-boy turned good for the love of the woman. But it’s also the story of our heroine growing-up to the point where she can accept, value and truly treasure his love. It’s a story of heartbreak and redemption. It’s messy, complicated, passionate and sexual. It is the story of our antihero falling our hero and winning her heart, while at the same time he slowly becomes the champion of the story. Their journey is far from smooth because of their personalities, their personal history and the circumstances. However, at the end, it is about two strong-headed people realizing that they have developed a deep and real connection.
And for me, S7 is the ultimate tale of this story, lived through their actions instead of their words. The stolen looks, the holding hands, the constant worry for each other, the self-sacrifice, the sweetness of their interactions, their mutual trust, support and respect and, very importantly, their mutual vulnerability, finally being able to be open and relay in each other. Words aren’t need when you can almost touch what they have created together by the end of the show.
So, yeah, as much as I loved Bangel when I first watched BtVS, I personally fell in love with the Spuffy story. Two flawed individuals getting together and falling in love despite their imperfections, knowing the best and the worst of each other, and still being willing and able to believe in each other and make it work in their own way.
