Amazon Prime Visa Rewards - Statement credit vs deposit

I only use this my Amazon Prime Visa card for Amazon and Whole Foods, so all the purchases on my statement are at 5% cash back. If I have earned $100 in cash back rewards and I choose to redeem it as a statement credit, that now reduces my Prime Visa statement balance, so is that now $100 off my statement that I won't get 5% cash back on? Is it smarter to redeem it as a deposit to my bank account? Thanks!
