in the current meta who is better? 
or 
cause I almost have enough to get one and I had this debate with my friend but we were also thinking 
so which is my best option also other ideas for other 3150 char's to get are welcomed
Those champions are so different from each other in playstyles I suggest you consider what you are going for... pantheon has always been a fighter to me, high burst but limited mobility, katarina is a straight up assasin and morde is a weird tanky mage... its up to your personal taste really. its hard to recommend you a champion if you dont state your preferences
