hello,
I give most credit for
SCJD. Unlike the other developer certificates it proves that you can develop software, not just remember specs and APIs.
SCEA (maybe the free SCEA 5 beta?) would make a great impression, but when you do not feel ready for that it is not a good idea. All the other certificates also make sense if they are a better fit to what you really need for your projects.
Or try something entirely different, like a Microsoft certificate.
