I have no idea what this question is asking.

'Engineering,' like 'art,' is one of those hand-wavey words.

In fact, I have a feeling you're actually asking:

"What are the coolest brands, as perceived by engineers, and why?"

Which is about as substantial as asking what the _pinkest_ brands are, or what the most _geographically-distributed_ brands are.

Or perhaps less so -- at least we can characterize 'pink' and 'geographically distributed' as reducible terms.
