SlumdogMillionaire, I have worked for both organisations and I disagree with jeez and Mr Cool. Although Deloitte is a stronger brand when it comes to consulting services (human capital, strategy/ops, etc) Capgemini has a stronger brand in the technology services space. From your post I'm guessing you are a technical consultant because I've not heard of an account / client management role in Deloitte's consulting business. I would also guess that your offer is not with the UK firm, in which case the distinctions is even less clear because in certain parts of Europe and Asia, Capgemini has a very strong brand (if it's a US based offer though, I would agree with jeez and Mr Cool).
