Accenture is very good.
But based on your interview experience and research on both firms which one is a better fit? Make a choice based on the firm & role which is a better fit with your career aspirations, values and risk profile. Choices are never perfect as with every other event in life. So remove the pressure for finding something perfect. Focus on giving your best.
I have provided plenty of insights on Accenture vs other firms. So have a look at this thread and others mentioned: https://www.preplounge.com/en/consulting-forum/ey-parthenon-vs-accenture-9952
All the best & congrats!
