While the Canon 470EX-AI can act as a slave in optically-triggered setups, the Canon 430EX III-RT can act as a master or slave in radio or optically-triggered setups. The flexibility that the 430EX III-RT's wireless features afford is immense, greatly increasing the usefulness of the flash. Also, those wanting a smaller/lighter flash atop their cameras, photographers who prioritize battery life and/or recycling time or persons with a limited budget will find the 430EX III-RT to be a better flash for their needs.

Who should opt for the Canon Speedlite 470EX-AI Flash?

Those photographers who appreciate the convenience of a flash that automatically calculates the optimal bounce direction will find the Canon Speedlite 470EX-AI Flash's auto-rotating head to be the deciding factor. Wedding / event photographers and those new to Speedlite flash use will especially appreciate the 470EX-AI's unique auto-bounce capability, allowing for flattering subject lighting with little effort or experience required. If optical triggering is sufficient for your multiple flash setup needs, the 470EX-AI can easily be incorporated as a slave unit. Few will find the 470EX-AI's slightly higher guide number to be a deciding factor, but the flash's extra power could prove beneficial in certain situations.
