People love to say it, but when we had GSuite issues at my previous workplace we spoke to GSuite support and had a resolution quickly. When we had GCP queries we spoke to our account manager who gave us a technical contact who escalated internally and got us the advice we needed. When we asked about a particular feature we were added to the alpha stage of an in-development product and spoke with the team directly about that. I've got friends who have had various issues with Pixel phones over the years and they just contact support and get a replacement or fix or whatever.
Meanwhile I've seen colleagues go down the rabbit hole of AWS support and have a terrible time. For us it was fine but nothing special, I've never experienced the amazing support that I've heard some people talk about.
We were a <100 person company with a spend quite a bit less than many companies of our size. From what I've heard from YouTubers with a million followers, they have account managers and they always seem to encourage talking to account managers.

I would rather deal with them than GoogleFi, because in that situation there was a certain point where I could give up and hand it off to our lawyers.
