Eclipse has its share of problems (and outdated UI and workflows), still I’ll happily use it over IntelliJ w/o hesitation.
Funnily enough, a lot of other (Java)Senior developers who tried both are fine with Eclipse, too.
Besides the astroturfing from IDEA which is really annoying, Eclipse integrates far better with standard build tools and is our last descend Open Source IDE (Netbeans effectively being a zombie at this time).
IDEA is already pushing/forcing their own solutions/build tools/etc. to up sell their shit, once Eclipse is gone, there will be no alternative and IDEA/IntelliJ will start the entshittifaction…
People really forgot what a shit show were the 90s, paying lots of money for commercial IDEs.
