This would be subjective to the individual. A perfect kiss for one person might be horrible for the other. A perfect kiss is not only has physical characteristics but it also has emotional characteristics. This means that a kiss with someone you love, in a moment that you are both enjoying will be more perfect over a kiss between two people who have never met before on a dance floor, for example. A ravishing tongue twist may not be a perfect kiss to some where as a peck on the cheek may also not be a perfect kiss to others. The only way to truly find the perfect kiss is to keep practicing!
