One month after VSCode installation and first test on Java projects, I realize that I haven't opened anymore Eclipse. Just today to make a screenshot...
I have not yet speak of the performance too. I have a decent MBP and Eclipse take always a couple of seconds to startup. VSCode start in less than a second.
Last, I am not only coding in Java but also Javascript. I have originally installed VSCode to replace Atom editor for my JS projects... So I am happy to be able to use a single tool for all my programming needs. It's faster and I am more comfortable to use a single tool for coding.
So just an advice: get a try on one of your Java project, you may be surprised to change your habits !
