What are the main differences between a drum sander and an orbital sander, and which one would be more suitable for my woodworking project?

A drum sander is larger and more powerful, making it better for heavy-duty sanding tasks on large surfaces. An orbital sander is smaller and more versatile, ideal for finer detail work and curved surfaces. For a woodworking project requiring precision and intricate sanding, an orbital sander would be more suitable.
