I liked the EE editor, especially the camera control, you just hold the "`" button on your keyboard and move the mouse around. This concept seems to be different in AOM.
Otherwise the premature interface of AOM looks saxy and easy to use. I am suspecting that you can work with multiple windows, i.e. you have a terrain window up and you're also browsing through the units window.
The AOM triggers are going to be similar to the EE ones (but easier i think), i am dead positive that theres graphic scale and graphic effect triggers in the scenario editor (look at the christmas screenies for proof)
I'd have to agree with intrepred that the EE scenario is very powerful and i mutch prefer it over AOK's. It was very powerful.
The only thing i hated about it is that theres NO HOTKEYS, you can't use the mousewheel to scroll, if you press B it won't jump you to the barracks on the unit page etc etc, it was very anoying and made things take forever to do.
The only worthwhile hotkey feature is the elevation.
Few people know this but,
When you're placing terrain, hold down the right mouse button and move the mouse up or down, the tile that the pointer is up will now increase and decrease in elevation acourding to which dirrection you move the mouse, this was very handy for making good hills, and you didn't have to go back and forth to the elevation screen to select which elevation size you want.
Also if you hold down the right and then the left mouse button and move the mouse around, you will be able to level terrain; the tile of terrain that the pointer was over will be "stretched" and level the other terrain to be evan with the terrain the mouse pointer is over.
These were very handy tricks but since the AOM elevation placement thing is very very different from any other game, i don't know if this will be possible to recreate in AOM.
In AOM you can make actual slope elevation. If you don't know what i'm talking about, picture a U cut in half, you can make slopes like that, and you still have the classic diagnal slope but you can position it in 180 degrees of slope, so you can have a tile facing straight up, you can have one go sideways, you can make a steep steep hill or a shallow little lump of elevation on the ground
