Which class is better in maplestory: dragon knight or crusader?

Since the big bang patch has occurred I want to know the current views towards dragon knights vs. crusaders. By "better," I mean which has more advantages (i.e. this class is better for soloing and dmg whereas blah blah blah). In addition, I already have a 91 attack clean blue screamer and a 95 attack clean omega spear. The omega spear is already 5 att above average the attack of omega spears, but the screamer is only 1 att above the average attack of blue screamers. I also want to know which class is more fun. Thanks for your time :)
