I don’t find getting into the multitasking switcher meaningfully harder on the newer devices— it’s just a swipe-up-and-hold gesture, which I’ll occasionally time wrong and end up at the home screen, but not often enough to be “painful” (and it’s just another swipe away if I do mess up).

What is vastly better on the X-series devices, though, is switching between your two or three most recent apps. Just swipe left and right at the bottom of the screen (on the bar)— this lets you flip between apps in the order that they’re in the switcher. This means I very rarely actually enter the full multitasking switcher in normal use.

(The other, minor benefit of the new-style gestures is that they’re all cancellable and map directly to finger movement, but that’s more of a “feel” thing than a major usability win. Makes it feel Apple-y, though.)
