“dealing with merge conflicts are a breeze” is an understatement. I don’t use IntelliJ typically in my day to day anymore, but the merge conflict resolution UI offered in IntelliJ is so far and above alternatives that I would still reach for it in a particularly complex scenario. VSCode’s UI does not even remotely approach how good IntelliJ’s is. I’m not aware of any UI that does merge conflicts as well as IntelliJ currently.
