Pros Putting all of the options on a single line works well for layouts with limited vertical space. The contained background with inset dividers visually connects all of the options.

Cons It does not work well for long words or numbers, phrases or prices. If you do choose to put those inside, plan for localization by offering less options. The horizontal space is very limited and even with less options you’ll still need to decide how your text will truncate.

Where did the 6 maximum come from? Each option within a segmented control needs to be greater or equal to the minimum tap target size. Math!

Radio Buttons

A radio button within a list item should be used for single selections of more than 6 options, a whole lotta content and/or unlimited vertical space. They are most commonly a circle outline that becomes filled upon selection at the start of the list item. iOS has created a new paradigm with the same meaning by putting a checkmark at the end and modern designs have adopted a highlighted stroke that goes around the list item to save horizontal space.
