I have to disagree with the theory here. Vendor certifications, held on their own, do nothing to make you look more/less professional. It all depends on the employer.
I mean, let's face it. If your employer or potential employer uses BEA WebLogic, then it's not going to be of any advantage to become certified in IBM WebSphere, unless there's some chance that your employer might be using it or switching to it (or if some other company you're thinking of looking for work with might be using it). It's better, in my thoughts, to apply one's energies towards general certifications save where specifics give a distinct advantage in the moment.
(There's another downside to IBM certs that hasn't been touched on - they expire. So getting a given version of the certificate only certifies you until the new version of the app comes out... and you might find yourself upgrading one or more times before it's of any use to you. Just food for thought.)
