Is FIS better than Deloitte?

I understand that both FIS and Deloitte are reputable firms in the finance and consulting industries, but I'm curious to know which one would be considered better in the eyes of experts in the field. Specifically, I'm interested in understanding how they compare in terms of their expertise in cryptocurrency and finance, their reputation for delivering high-quality services, and their ability to adapt to the rapidly changing landscape of the industry. Could you provide some insights on these points and help me understand why one might be preferred over the other?
