Imo, it would have to depend on the nature of the cinematic. If you’re looking to emulate “gameplay” in your demo with your character experiencing events happening from the player’s perspective, then you would probably go for the latter, however if you’re looking to tell a cinematic story in your demo, the obvious choice would be to use Matinee for all animation control (though if you’re looking to upgrade to 4.12 I highly recommend using Sequencer).
