Need help choosing between Sun and MS Cert

Hi,

I’m trying to choose between the Sun Certified Programmer or an MCAD(VB.NET) certification.

I’ve been programming with VB for more than 9 years now. I’ve had programming experience with Java (JSP, applets, servlets, standalone apps) for just over a year.

Can you guys suggest which certification path I should take first? Which would serve me better in the long run? I’d surely appreciate your advice!
