When the introduced the $10 / user tier (up from $5), $5 gsuite lost at least one feature that I use: email content filtering. It was implemented in a pretty hard-to-find place, but was effective and had enough functionality to catch, e.g. social security numbers and credit card numbers.
If a team was already using the feature they got to keep it for an extra year or so, but otherwise you had to upgrade at double the price to have the feature.
That being said, it is now implemented in an easier to use way.
Don't recall details, but I believe there were a few other minor functionality losses of that type. I had already moved to the higher tier for unlimited storage and data retention tools.
There's a feeling of a stronger and stronger push to get per user revenue up and up with the new Enterprise level functionality coming at "contact us" pricing.
