Why digital is a strong first choice
Digital yearbooks are free to start, easier to edit, and easier to finish because you do not have to commit to printing, quantity, or cost right away.
You can build the pages, use premade templates, adjust text and image boxes, and see what the full book looks like before deciding anything else.
Why physical is still a great option
A physical book feels more final, works well as a gift, and can be the premium version if you know you want something printed and tangible.
The good part is that starting digital does not compete with that. It usually makes the physical version better because you edit the book first and print only when it actually feels finished.
