NTT Data vs EY need help deciding (5.5 YOE, both client rounds cleared)

Currently at 16.5 LPA fixed. Have offers from both:

NTT Data – 24 LPA fixed, client is a US bank, fully remote

EY – 20.25 LPA fixed, client is American Express, 3 days/week onsite at client office

Cleared client-facing rounds for both. NTT Data pays more and is remote, but EY has the brand name and Amex as client. Which would you pick and why? Anyone worked with either client or company culture-wise?
