I think the Basic Email Notifications are good. They give all the pertinent info and are super easy to use.
In fact, the only time I don't use them is when I have a record rule that also inserts a new connected record. In that case, I have to manualy add all of the form fields to the custom email in addition to saying "also inserted a connected record".
Please add "Inserted a connected record" or "Updated a connected record" to the basic email notification.
Alternatively, add a "Basic Email Notification plus comment" option.
