AV1 offers several key advantages, which can make it a better choice in certain scenarios:

1. Improved Compression Efficiency: AV1 provides better compression efficiency, which means it can deliver the same video quality as older codecs while requiring less bandwidth. This is particularly important for recoding, as it can reduce the data transfer and storage costs.

2. Better Video Quality: AV1 is capable of maintaining higher video quality at lower bitrates, which can lead to a better user experience, especially in situations with limited bandwidth.

3. Support for 4K and HDR: AV1 supports high-resolution video formats, including 4K and HDR (High Dynamic Range), making it suitable for modern content delivery.

However, there are also some challenges and considerations when using AV1:

1. Hardware Support: AV1 encoding and decoding can be more computationally intensive compared to older codecs, which can be a limitation on devices without hardware support for AV1.

2. Encoding Complexity: Encoding content in AV1 can be more time-consuming and computationally intensive, which might require more powerful hardware.

3. Compatibility: Not all devices and software support AV1 out of the box, so content providers may need to ensure fallback options for users with older equipment.

In conclusion, AV1 is indeed a good video codec that can offer better compression efficiency and video quality.
