(Is answering your own thread uncouth?)
I forgot to mention: This is for the on-site EF reviews, not the off-site. But, the off-sites can give their vote if they like.
I prefer the Extended over the Standard. It narrows my focus on what I'm supposed to write about in a particular section, and it allows me to work on different sections at a time, as opposed to just the entire thing. Also, the Extended reminds me that I need to talk about, say, the texture of a product, in which I may forget to write about in the Standard.
So, yeah, Extended, always.
