First of all it depends on what level of education you mean. If it’s a bachelor it’s not a big deal but consider the syllabus Computer Engineering usually imply both Software and Hardware engineering, while IT is usually about software, so it’s about you to choose.
Regarding Computer Science I doubt it differs much from Computer Engineering as it usually has the same syllabus as CE, having just a different name. Personally I prefer Software things and the work opportunities for Software Engineers are greater but it doesn’t mean being Computer Engineer you know less than Software one, as I told it really depends on a syllabus of a university.
