If you're using it for hot object storage and not as a cold backup, Wasabi has by far the worst egress situation of any object storage provider. They have "free" egress because egress is capped at 1 full retrieval per month, and they'll just ban you if you use more. R2 has actual, legitimately free egress. I think there's almost no overlap in use cases between Wasabi and R2 even though they're ostensibly both object storage providers.
