Since I left last time Real Debrid threw pirates under the bus:

I used https://alldebrid.com/ but wasn't quite as good at the time. Maybe it's gotten better since RD 1st exodus.

Premiumize is what I switched to and use now. Has as much cached as Real Debrid did during their peak as far as I can tell over the past year or however long it's been. But it's more expensive since it's a combo service not just Debrid and it's a lengthy feature list that includes cloud storage with many ways to access it, VPN, and Usenet amongst other stuff: https://www.premiumize.me/features
