Also in their behind the scenes for their "Shot on iPhone" videos, usually they show Resolve, Premier or Media Composer, but rarely Final Cut.
In the end, their creative software is just ok; it's probably best to not rely on it too much if you don't want to get stuck. After they canceled Aperture for no good reason and destroyed the iWork suite while taking forever to even manage feature parity, I'll never rely on or recommend Apple software.
