Thanks for responding, that makes a lot of sense.
I think generally what one gets used to has a big impact on preferences.

I'll say, an easily accessible, reliable gesture for side menu sounds nice. It feels like this was either abandoned on Android or left up to developers who mostly abandoned it. I remember struggling to get the side menu to trigger instead of back navigation and it not working near reliably enough. So I've been trained to always use the hamburger buttons that, ironically, are hard to reach in the top left corner in most apps. To be fair, I feel like I hardly use one menu interaction for every 100 back actions, so the latter being ergonomic is a lot more important to me.
On that point, swipe from left to go back seems quite annoying. I go back all the time, and having to move my thumb across the entire screen is a pain. I almost never need to go forward, so having that be the more accessible gesture seems weird. I'll concede that having a gesture for it at all is useful and Android should add the option.

I never felt like the swipe to go back is too sensitive, and if you accidentally trigger it, you can simply move your finger back towards the edge before letting go to cancel the action. You can also configure the sensitivity in the settings. The feedback that you're about to trigger the action is probably not as obvious as on iOS though, and likely less elegant.

I think both Android and iOS would do well to let users customize these interactions more to their own needs.
