Which is the best Macro?

Imacros for firefox is awesome, the imacros browser sucks i hate it, its slow and doesnt have any complex features.
Im looking to start using a macro with more complex features, anyone can recommend which is the best?
Ive searched and so far a few macros i keep hearing about is... JitBit, Automate Everything, Automate9

If you're looking for a disposable macro, JitBit is hands down the fastest, easiest way to do that. But it doesn't use javascript, so the bot isn't very portable , and doesn't have some advanced feautures, which you could get with any python or javascript based macro player.

Imacros for firefox is a little less user friendly, but it has the advantage of only playing in the browser. This leaves you space to do other things in other windows.

It all depends on context of use.

iMacro is fast if you do little settings like hiding java scrip execution, element selection and finally using java script inside the code.
