As you said, SNS is mostly covered with PubSub but SQS and any sort of RDS for something other than MySQL are absent (notably Postgres). I like GCE a lot and we use it at $work but there's no excuse at this point to not have feature parity.

PubSub should handle all of your SQS needs and then some. It's a weird combo of SNS and SQS. Has topics, too.
