Which career path is comparatively less difficult to crack: UPSC IFoS, UPSC CSE/IRS, SSC Income Tax Inspector, or NEET?

​

Hi everyone, I wanted to ask something.

Which career/exam is comparatively less difficult to crack among:

UPSC IFoS

UPSC CSE (IAS/IRS etc.)

SSC CGL → Income Tax Inspector

NEET → MBBS/Doctor

I know all of these are highly competitive, but I'm trying to understand the difference in competition, preparation time, difficulty level, and chances of selection.

For someone who wants a stable and respectable career, which path would you recommend?

Also, how does NEET → MBBS compare with these government exams when you consider the entire journey, including the 5.5 years of MBBS?

Would really appreciate honest opinions, especially from people who have attempted these exams or are already in these careers.
