In my opinion, by all ramifications, CBN is better off even if the pay is lesser than that of Globacom; for obvious reasons.
However, it all depends on what you want from your chosen career. That is, if the job you are being offered is what you'll enjoy doing, as well as gives you room for growth and improvement on your career, then go for whichever offers you that.
Moreover, Pray fervently about it and follow your heart!
Goodluck!
