Indeed the right question to ask is what your objectives are, where do you want to go?
I would not do TOGAF if you already have SCEA. Don't certify yourself to death on archtecture, after all, it's only certification and experience as an architect trumps it (almost) always. Also I don't think it's very efficient: Many things that TOGAF should teach you,
you should already know if you have SCEA. Finally, to me, it looks a bit suspicious to get multiple architecture certifications. Prospective employers might think: Which one of your architecture certifications is no good, so that you needed to do the other one? Exactly how unsure about your architecting skills are you, that you need multiple certifications?
Assuming you are or want to become an architect and considering you already have SCEA, I would look for training/certification on methodology or quality assurance. E.g. CMMI or Scrum certification.
The
ThoughtWorks Technology Radar says to hold off on Scrum certification (see Jan 2011 edition). I haven't figured out why that is yet (you need to scrounge earlier editions to find the motivation), but it might be that Scrum certification specifically is not a good idea right now. I'm just giving you my general ideas. Hope it helps.
