Emberquake VS Flame Hammer

Does skills look so familiar, they seem to do exact same thing, and they seem to have quite the same stats when they are maxed out so... whats the difference? is there any sence of maxing out 2 of them ? or should I just max out the Flame Hammer and ignore entirly the emberquake ?
Is there a sense of using them once I hit with it then with that ? this skill is so similiar to Flame Hammer in my opinion that I dont even know why it is there!

Here is said thread.
Where words fail, music speaks.
And other o with Emberquake.
The truly power of Flame Hammer is when using charge; better damage on single target ( of course when using charge), less mana than Emberquake.
Emberquake have more range and better than FH on crowd clear, no need charge to be use.
