We can install plugins into Eclipse to get all the features of Spring Tool Suite. However, STS comes with Eclipse with some other important kinds of stuff such as Maven support, Templates for creating different types of Spring projects and tc server for better performance with Spring applications.
I like STS because it highlights the Spring components and if you are using AOP pointcuts and advice, then it clearly shows which methods will come under the specific pointcut. So rather than installing everything on our own, I prefer using STS when developing Spring-based applications.
