Having obsessed over both, I am going to say... Depends. Yes it is a cop out answer but this is also a ridiculous question.
Elder Scrolls was about a singular character in a world, thus everything could revolve around him or her. You could be a stealthy bugger or a sword swinging bastard or a spell flinging wanker. You could even do all three if you were a hybrid whore like me... But the absolute versatility of what you could do made it all very... Bland. Comparing Morrowind's combat to Oblivion's found me liking the idea of using my reflexes and hating absolute adherence to stats for a hit or miss. Which is why I like combat better in Oblivion vs Morrowind. I can think and react fast, the game rewards me for that. Morrowind didn't.
Then you have Dragon Age... Which is more tactical and makes anything you do feel special in regards to combat or spells. You can't exactly feel like a ninja like you can in Elder Scrolls but I am willing to forgive them since they made magic interesting for me again. Every fire spell looked pretty much the same in Elder scrolls, etc. Flash boom, done. Also, Dragon Age has specializations which gives you choices that have impact whereas in Oblivion or Morrowind, you could honestly just have every skill at once on every character and there was no reason not to...
Playing Dragon Age Origins felt like playing D&D, I was interacting with characters and my choices had impact on my progress. Playing Elder Scrolls felt like tossing an idea together and exploring everything with unlimited time to do so. Both are good, Dragon Age Origins is for feeling cool. Elder Scrolls is for getting your explore on, also cool.
