Hey,
It entirely depends upon your calling. Both IT sector and Civil sector are equally good and cannnot be compared on any scale.
IT industry is one of the most popular sectors to work in if you have interest in web and internet technology or database management. The IT sector also influences the working of other sectors or industries either directly or indirectly. While,in IT sector you will get to work in air conditioned offices,Civil Sector will have you near the construction sites,where you will be required to supervise the work,design and analyse public projects like dams,highways,canals and bridges.Anways,the pay is good in both.
Hope this helps.
Good luck.
