Deloitte digital vs Accenture Interactive

I have an offer for a opportunity for a Manager level position within Deloitte Digital but am currently a Manager at Accenture within it's Accenture Interactive arm doing Marketing Operating Model Redesign and Customer Experience Transformational work. Is Deloitte Digital's business selling this type of work, or is it mostly tech? I can appreciate the operational efficiencies these tech improvements provide but it's not my expertise tactically speaking and want to make sure I'm not making a jump that's going to completely change the type of value I provide my clients. The partners and senior management I've interviewed with have been great, but want to make sure I'm not just being "sold" on the firm. What can you share about the type of consulting focuses or kinds of value propositions Deloitte Digital pitches and provides its clients?
