And lose access to the consumer offerings for which Google isn't prepared to offer enterprise management features and/or support, or which just don't fit into their enterprise vision. Every time a new consumer service or feature product is released, complaints start from G-Suite customers about not having it.
Which isn't a big deal, perhaps, if it's not a service with interacts with others on your account, so you can just use it on a different account, but for things that you want to integrate together splitting different services to different accounts because not all of them are supported on G-Suite makes the services on both accounts worse than they would otherwise be.
Google One is the offering directed at this, though I don't know how good the support component is.
Same for Google Play store as a developer; didn't matter that I had a $5 account, different department so back to robo-emails you go.
But Fi is a service that the customer is paying for, they should not be subject to automatic lockouts without any way to get it resolved other than to "start fresh."
I would not recommend G Suite to anyone who is a consumer or household any longer.
Yes, none of the "Family" products are available for G-Suite. That being said, all of the functionality beyond saving money is there with G-Suite. The saving money part is important, don't get me wrong. But sharing photos, seeing your "family's" (aka, your G-Suite organization's) stuff, etc, that's all there. Its just packaged differently, and in a way that's more expensive and substantially more powerful.
YouTube Music is definitely available on G-Suite. So is Google Fi; I'm on a Fi device on my G-Suite account right now (they enabled this early 2018 IIRC). Google Spaces is a discontinued product that isn't available for anyone.
The Google Home and Assistant is the only area today within G-Suite I've seen really weird behavior because I use a G-Suite account. Things like accessing your calendar just don't work right, and often result in errors. That's a very valid issue.
There are sacrifices to both approaches. I will gladly pay the extra money to, in turn, get access to a higher tier of account level support, unlimited storage, and the custom domain name. There are also a few products that are only available to G-Suite customers. CloudSearch is a single omnibar search service that does deep, filterable search on every resource in your G-Suite across all of their services (Gmail, Calendar, Drive, etc). Vault is also cool; I have rules set up which retain emails indefinitely, so even if I delete them from GMail they're still exportable from Vault. The Google Titan Key was also a hardware product that was only available for G-Suite customers for a while.
It's a no-brainer. It sucks that their personal account support is so bad, but there is a solution.
