EMD/PMD vs good sounding domain name?

So... I've been reading a bit here and there about EMD's / PMD's and I wonder: are they any good for ranking?

The site will be based around a 10k+ keyword sub divided by different categories. Can't decide to choose a sounding domain (got one available) vs a name that contains the full keyword with "the" or "a" in front of it which might sound a bit odd to some.

It will be a site based around reviews + amazon affiliate program, would love to hear your opinions .

No guru available ?

I have sources stating brandable is better, while others state EMD is better... My domain is not completely random, it does contain a very broad keyword I'm targeting (but not the niche itself).

Still no-one?

I'll add a bit of information to make my question more clear.

I'm targeting mainly 3 words for this site.

Word 1 & 2: Very niche related
Word 3: The general topic.

3 Options for the domain:

WorldOf(word 3).com
or
The(word 1)(word2)(word3).com --> this will result in a +- 20 letter domain though...
or
(word 1)(word 2)(word 3)Review.com --> will result in over 20 letters.

The 2nd and 3rd option are more targeted, but in my opinion are too long to not look spammy . Option 1 is not very niche targeted, but looks more natural.

Anyone?
