I agree with PV in terms of the relationship side of things...it's not a contest.
Kissing wise...I don't know...Bangel looks more comfortable? More romantic? Less desparation and "smacking" as Giles so rightly put it.
But then maybe if I were getting kissed like that I wouldn't care what it looked like either 😛
Look at it this way: Angel's kiss is a Diet Coke. Spike is a triple deluxe chocolate milk shake with whipped cream and two cherries on top. One's better for your diet, and the other's pure unadulterated sin. Which do you prefer?
Edit:
Folks, on reading back on this thread, I see that I have led us all astray from the original subject again, and I guess that I should apologize. I honestly don't start out to do this, it just winds up happening, especially when I start verbally sparring with Miss K. It was bad enough when we were just two people participating in a mutually cared for subject, but now, if I understand the lady's new duties, it's her job to keep these things on subject, and the very last thing I would ever want to do is get a friend in trouble. Therefore, if no one objects, I would like to concede the point :Angel kisses like a house on fire and every time he does, Buffy melts like a birthday candle.
And Miss K, I promise you that if I stray off subject again (and you KNOW I will, I'm a Spuffy addict) I will take no offense whatsoever if you do your job and smack me between the eyes with a baseball bat if that's what it takes to straighten me out.
Once again, my most sincere apologies to everyone who were trying to carry on an interesting conversation only to be interrupted by an old man's obsession.
