Literally,
your assessment of the ergonomics of this
specific case is subjective. If you
really want to split hairs, the BB10 swipe gesture is actually longer in both time and physical motion. You don't start in the middle of the screen when you're in an app, you reach to the bottom. Then you swipe up and to the right, with a noticeable pause during the first half inch of the pull to the right. Or, you're reaching for one of eight open apps located on the screen with an extra swipe if you're going for the second four. Or perhaps you're needing to launch an app, then you you're swiping to the right at least once.
By comparison, Android allows for the icons to be completely rearranged suit your needs. I've got my daily-used apps in two rows on at the bottom of the screen, I can either drop the notification shade from the bottom row or tap the home button and travel to one of those icons in less than an inch and far faster animation time. Most used email functions are already on-screen, so I don't need to spend time accessing them. Nor do I need to open each message, last message in a thread is already expanded. I'm far more efficient now than I was with BB10. (CB email example below)
Do I hate BB10? No. I keep my Z10 powered up because I'm hugely nostalgic. But I do recognize BB10's limitations and recognize Android's advantages, and put them to use.
