There is a bit of more latency when using S3 compared to HDFS, but it's not bad and the benefits overcame that. We do have a couple of jobs that store some intermediate results in HDFS, but in the end everything lands in S3.
We encountered a few issues with S3 at the beginning mostly around the eventual consistency, but nothing that could not be fixed.
