Yes, Apple's functionality seems best for casual users (ie, my parents) who generally only use safari on their ipads and mac.

iCloud Keychain is a better experience on iOS because only Apple can extend Safari - If you're using 1Password on iOS, you can't do the equivalent of "CMD+\" - you have to use the launch the 1P app - which breaks the workflow.

I don't see me moving away from 1Password anytime soon - though the ability to have multiple agile keychains in a single 1P session would have me pulling out my wallet - been waiting for that for awhile.
