B2 pricing is 0.5 cents/GB/mo, R2 is 1.5 cents/GB/mo.
B2 egress is 1 cents/GB/mo with 1GB/day free, R2 is free.
If your cloud storage is for backups, B2 is likely to be less expensive because backups are rarely downloaded and their 1GB/day of free egress is enough to do backup maintenance to optimize storage.Cloudflare's CDN can proxy a B2 bucket to get free egress and maybe faster downloads (haven't needed it myself):

I'm a big fan of B2 because:
- they have low pricing
- they have simple pricing
- they don't use gimmicks: minimum storage time, minimum file size, minimum payment per month, etc.
HashBackup was one of the first B2 integrations and I've never had problems with it.
