What are the differences between a DI box and an interface, and which one would be more suitable for my audio recording needs?

A DI box is used to convert high-impedance signals to low-impedance signals, while an interface is used to connect audio equipment to a computer for recording. If you need to record instruments like Guitars or keyboards directly into a computer, an interface would be more suitable. If you need to connect instruments with high-impedance outputs to a mixer or PA system, a DI box would be more appropriate.
