I find the passion behind IDEs a bit bemusing, I've never really felt the strong benefits of IntelliJ over Eclipse, although using Eclipse for quite a few years means the burden of changing is reasonably high. IntelliJ certainly had very vocal advocates, the Thoughtworkers I worked with pushed it very, very hard. Eclipse I find to be a mixed beast; if you get it into your 'sweet spot' or ideal configuration, it can be perfect. Mine is Gradle based projects (the integration seems to work fine, or use the CLI), and keeping things simple with POJOs, a bit of Spring Boot etc for more complex things. I've worked with truly horrible projects/configurations e.g. Websphere Application Developer which is/was based on Eclipse but with everything and the kitchen sink bolted on. It was slow, buggy, took 30 minutes between firing the IDE up and being able to work etc. EJB's, DB2 database access etc - just a nightmare. So to me they're both sort of what you make of them; I find the Eclipse plugins to meet all of my needs well, the times I've tried IntelliJ or paired with someone that uses it, I don't agree with the purported benefits.
