What is a better career path, Software Development or IT security?

ive graduated with a software engineering degree and was planning to do either c# or java. firstly, i cant decide between the two so can someone tell me which is likely to bring me more success, given that i pursue the given certifications. also ive been told IT security is a good field to go into, specifically taking the CISSP certification. Any guidance would be appreciated.

I say Software Development, i don’t have a reason, but I will be going into university pretty song, and from my perspective it choice the Software Developement
