I don't think there's anything to be excited about with the future of iOS, just more of the same for as long as regulators can be kept at bay. Maybe even sillier if the rumours are true the folding iPhone is blocked from running iPad apps lol.

Hopefully Ternus will be less uptight about ancient iOS restrictions, I want my iPhone to be every bit as useful as a MacBook Neo if I connect a monitor/mouse/keyboard.

Better for voice search/assistant? Probably Android.

Better for voice dictation? Android.

Better keyboard? Android.

Better integration with other same-os devices? iOS.

Better UX? Likely whichever you’re used to.

Better for what?

I would say its pure preference at this point. Both operating systems have converged towards each other in the last few years, where nowadays it really just comes down to your taste, the ecosystem you are in (or want to be in - ), and whether you value having potentially a bit more freedom (with some devices that make it easier to flash custom ROMs/Kernels).

What should be mentioned though: Android is not anymore as tinker-friendly as it was 5 years ago, a lot of OEMs make it hard to even unlock your bootloader's, Google made it almost impossible to run anything custom (due to Play Integrity) without you losing access to half of your apps - so in practice, I feel like Android has not even anymore that specific anymore.

If you have special preferences, there might be a specific OS/Phone that can accomodate you better but that is something you'll need to know.
