The Core Spring 4.2 certification may help in Service base industry. Also will help you to be through with your knowledge in Spring Framework. It is good to have this certification because it is a perfect way to showcase your knowledge and it will be valid for a long time.
I would suggest to do some project using Spring Framework first or may be contributing to open source who are using these stack, then once you are comfortable with the technology, then go for the certification.
By the way, here are the differences between Spring 4.x and 3.x
Spring 4.x:
- Removed Deprecated Packages and Methods, check out the API Differences

- Java EE 6 and 7 or above is now considered the baseline for Spring
- Framework 4

- Core Container Improvements
- General Web Improvements
- WebSocket, SockJS, and STOMP Messaging
- Testing Improvements
Spring 3.x:

- Custom @Bean definition annotations in @Configuration classes
- @Autowired and @Value to be used as meta-annotations
