Using flexbox - is it relevant today?

Question

Cross browser

I asked this question on stackoverflow, but it was tactfully explained to me that I need to go here.
If my question does not apply here, please do not swear. I don't have much experience in dealing with such resources. However.
Gentlemen layout designers and frontend developers, tell me how correct, relevant and justified it is to switch to flexbox? It is clear that provided that only modern browsers are supported (including the donkey from the 11th version).
Why I ask - on the one hand, on stackoverflow, for example, and here, whatever the question is about layout - then flexbox, which means that colleagues actively use it. On the other hand, the topic of bugs, properties not working, etc. is raised through the question. So what is flexbox layout now - fighting bugs and hitting cross-browser compatibility, or is it a nice way to make your life easier? How often do you use this technology yourself, in what cases do you recommend it, are they convenient in the subsequent support of the site?
And it seems to be desirable, and prickly. And the feeling that I got stuck somewhere in the last century with my inline blocks and alignments. Many thanks in advance for your reply!
