I have the same question, and can’t find an answer anywhere here or on Google (searching leads to this post).
I know that Group is the newer field type. Is there a performance gain in using Group?
Say I help Jerry Seinfeld with a website, and I’ve created a field group entitled “Comedians in Cars – Shows”. In addition to the fields Guest, Place, and Date, I have a field Car and want sub-fields of Make, Model, Year, Photo, and Description.
Is there a benefit to using Group rather than Flexible Content for the Car field?
