Entirely anecdotal, but we've been using Google Worksapce since it was called Google Apps and my experiences with their customer support have been fairly positive. At one point, I had a rep chat with me for about 45 minutes trying to figure out a bizarre problem, then we figured out that it was likely something outside of Google's control and instead of saying "we can't help with that", he setup a call about an hour later with an engineer and himself so we could verify. Turned out to be a DNS misconfiguration (a TXT record was double quoted from what I recall), but we struggled to figure that out and after a 30 minute call, we had it fixed and they emailed me a week later saying they had updated both internal and public support docs to include my edge case and had introduced a more descriptive error.

It's not the best support I've received in the IT sector (Linode has always been my favorite for that; I worry Akamai will ruin that though), but it was pretty close.
