No, seriously. Blackberry OS 10.3 is pretty damn solid. I don't have any issues with system stuff crashing on my Q10.
I do have some apps crash, but that's the app developer's problem. Not much the OS vendor can do about that.
I initially got a Blackberry because I wanted a hardware keyboard, and couldn't find an Android with a good one. However, after using the Q10 for a while, I would hate to go back to Android even with a good keyboard - I really, really like the Hub and the way gestures work.
Blackberry's voice assistant isn't as flexible as Google's or Apple's, so that might be an issue for you. It works well within what it's designed to do, though.
Apps can be an issue. Usually for anything I want an app for there's one or two apps, probably paid, versus thirty free ones in the Google Play store. I can access the Amazon Appstore for Android (comes with the OS) and sideload Snap, which lets me use the Google Play store, but the phone lacks some Android services so a good chunk of apps don't work. The Android runtime's pretty solid, so the apps that don't need Play Services work well.
