I'll say this, I've noticed Raleigh and Charlotte seem to be growing at similar very high rates with transplants coming from all over but I've noticed black people in particular gravitate to Charlotte and seem to view it on a much more desirable level than Raleigh where as white people, its kind of even. This is just casual observation though. Charlotte is a bigger city with more entertainment options but Raleigh is a place as well. Its probably the safest "big" city in NC and very family oriented. Good schools and was also ranked the 2nd most educated city in the country

Good stable economy. Big industries are government, medical, education, and IT/Technology. With Raleigh, you have to view it as part of its overall metro (the Triangle) along with Durham, chapel hill, etc which gives it a bigger boost. On the downside, it can be a little "stale" and kind of has a generic "any town, usa" vibe. Nightlife is kinda bland. Also getting more an more expensive along with the population growth. But if you want a nice, safe, place to raise kids/start a family, with decent economy, and basic general amenities Raleigh is a great place.
