Yes. That is more important than being born in a Deva realm.
However, it depends on one’s current status.
1. If someone is still on the mundane path, engaging in meritorious activities such as giving is essential. That will enable one to avoid being reborn in a “bad realm.” Of course, one must also actively learn critical concepts like Paticca Samuppada, Tilakkhana, etc.
2. If one is on the Noble Path, one must focus on progressing on the path by cultivating Satipatthana/Anapanasati. Of course, one must also engage in meritorious activities, as well as keep learning Dhamma. They both help cultivate the Noble Path.
Since many people are uncertain about their status, it is best to pursue both.
