Slightly higher latency. I've seen about 20-30% increase from S3 to R2. But the bill is magnitudes lower.
Agree with the KV point, Upstash is the same. But I just use dragonflydb on a single VM. No point paying for transactions.
Hell, S3 could have 20ms latency and it wouldn't matter since I can't afford it.
