To be honest, yes clickteam fusion more powerful than C2. But the prices is also expensive, you need to buy separate plugin and upgrade to developer version if you want to show the ads on your game. If i have more money, i definitely buy Clickteam fusion 2. But alternatively you can learn playmaker on Unity instead, it's just $45 on sale. Playmaker is a great tool to make a game without writing any single code on unity. Lately, i got custom action that you can animate any sprite with just 1 window without using unity animator mecanim, awesome!
I hope C3 will really really best game editor out there, some basic feature like transitions, tween, moving object.
