Depende sa field mo or gusto mo boss. You're comparing apples and oranges here. True na both are in the computer and tech field, pero the difference lies on the focus of the field. CS (my major) focuses more on the back-end (programming, AI, automata) and theoretical aspect (algos and calculus). Mostly coding and theoretical stuff ang inaaral namin diyan. However for IT, take what I'm about to say with a grain of salt since I'm CS major rather than IT, are mostly on the front-end, design, and business application side of computers. I hope nakatulong to sa pagpili mo!
Edit: Banned acc pala tong nireplyan ko, pero kung sino man makakita neto and may same question, sana makatulong din
