Hate to be blunt, but like Ghengis_John says: It's all about preference.
I'm biased to say the Soul Calibur series is the best fighting game imho, but I wouldn't make a topic to flaunt about it. I mean, if you feel it's better, then there's not really much to discuss except worry not of what outsiders think of it. Majority of 8wayrunners that read this thread would probably shove a comment to your face like: Well duh, of course it's the best. Close the thread.
You can try to reword and articulate, but you're basically sugarcoating it with synonyms. Such as what aspect is SC better than blah blah blah is the sugarcoat. SC is better than most FGs is probably what you truly want to believe in.....which I would agree but wouldn't flaunt so haughtily about...
