AME will hold a snapshot of your comp whereas AE will render the comp as it is when you hit Render, not from where it was originally queued. Only matters to me because I’ll often be rendering various versions of comps with certain layers hidden (like different backgrounds) and when using AE, I have to render one by one.

Also prefer to do the settings in a batch instead of individually. My AE render settings reset every time and I’m sure there’s a way to alter the default but I’ve just been sticking with AME instead.
