Hi Karsten,

By now, you should already know my opinion on this: Bombing is about using every reasonable theory/strategy.

Both of these are reasonable, therefore, we want to try to use them both.

Have one site where all the incoming links use the same keyword anchor text, have another site where the links use a wide variety, but related, keywords.

You can even toss in a third site that uses the same keywords, but also sometimes adds another keyword or two:
green widgets
small green widgets
fast green widgets
green widgets for sale
green widgets for rent
round green widgets

Again, advice for one niche may not work for another. And, things may change in the future. By implementing "every reasonable strategy", we can cover as many bases as possible.
