I use both. IntelliJ being a paid personal subscription. I like both. But VsCode excels in their remote editing capabilities. Sometimes I work on code that will only compile on a Linux and I am on a Mac. It is not just remote debugging - the whole environment including language server works flawlessly via remote while making you feel like local development.
It is good for two good IDEs to survive. I don’t want one of them to win. There is room for two.
I only wish the opensource development model of plugins (for both IntelliJ and VsCode) doesn’t come to bite us one day with a rogue developer inserting malware. The whole review/reputation system should be like Apple App Store
