This depends on what is going on the flag.

The feather shape draws attention from its movement in the wind. It’s best to use it for brand awareness such as logos and simple messaging which is easy to read if it’s moving. We find feather flags are most effective when a few of them are fluttering in the breeze next to each other, making them impossible to miss.

The teardrop shape offers a focal point for your logo, increasing awareness of your brand. Since the material stays taut at all times, the message is always clear to read. The hanging shape has a larger surface area to hold a more detailed message. It can flutter slightly in the bottom corner which hangs loosely but also keeps its shape with help from the horizontal bar along the top.
