  • Allows customizable layout that can be very complex(example: different sizing of each cell)
  • Supports multiple cells in one row
  • Provides horizontal scroll direction, eliminates the need to create scroll view to achieve the same effect
  • Supports custom animations for cells based on layout
  • Can implement drag and drop functionality
  • More options for headers and footers settings, it does not need to be anchored on the top or bottom
  • Does not include blank cells
