Teacher Credentialing

I just found out today that my application was accepted to get a California teaching credential, using the Michigan one that I already have. I am now certified in both states... however I need to do some more research now and figure out/decide which one will be easier/more beneficial to get the necessary requirements to renew it/ get the next level one. I have less than 3 years left on my Michigan one to get the requirements and 5 years for California. However, I think the Michigan one may still be easier to renew... oh the joys of being a professional!
