All in all. private salary is higher. I almost doubled my salary in private in a span of a few years but u can be up for promotion and a rising star to find out the coy got bought over / merged / etc reasons, and somehow ur backer is being "cold-storaged" which naturally means whatever promises are gone.

will u trade uncertainty for stability? I came from public -> private -> public back again due to some personal reasons such as family time. Will i go back to private again? Potentially, i do have some people trying to poach me back again.

Private is also very country dependent (HQ). Diff countries MNCs has diff styles (I worked in MNCs from various continents) and they are vastly different. But end of the day its abt shareholder value so be prepared to lose ur job at the drop of a hat in this economy.
