What are the advantages of working with the Big 4 audit firms?

[kuldeep]

I often hear about the Big 4 audit firms—Deloitte, PwC, EY, and KPMG—being the most trusted names in auditing and consulting. I understand they handle some of the largest clients worldwide and are known for their strict compliance and global expertise.
However, I’m curious to know: what are the main benefits of hiring or working with the Big 4 audit firms compared to choosing a smaller or mid-sized audit firm? Is it mainly about reputation, global presence, or do they also bring significant cost/value advantages?
