All four — Grommet, Tab Top, Rod Pocket, Sleeve Top. For the tall vertical repeat of the Icicles pattern, a heading style that creates a clean, full hang (Grommet or Sleeve Top) lets the complete pattern read from the top of the panel. More gathered styles (Tab Top, Rod Pocket) bunch the top of the panel and partially obscure the first part of the repeat — this is a matter of preference, not a design error.
