Question about differences between iOS & Android in work environment

Sorry if this sounds like a dumb question, but I'd love to hear from an IT admin's point of view to help understand the differences. My employer now requires all employees to register their personal phones so they can be managed, if they want to use it for checking emails/calendar/chats/etc.

The employees with Android (including myself), had it super easy. It automatically prompted to setup Work Profile in order to continue using the work email app, and it finished setting up in less than 2 minutes. And any work apps now have a little blue briefcase on their icon, and I love how in the command center, you can easily toggle on/off the Work Profile to pause all work-related apps (for example on the weekend or when you go on vacation or just when you want to not deal with work anymore). And the employer can't see the personal apps or data since it's stored separately.

However, I noticed for my colleagues with iPhones, it was a lot more tedious. Those employees had to follow this whole document of steps to manually install some certificate to set up MDM. And then if they were lucky to get it working, there's still no app separation so the employer can still see all their personal apps and data?

I already knew that iOS doesn't have a user-friendly Work Profile like Android, but is that normal to get employees to do it like that? I would have assumed with how popular iPhone is, there would be a more simpler/automatic way for setting up personal iPhones for work. I've always heard on this sub that iOS is easier to manage, but from an employee's point of view, it doesn't seem that way (at least not the way my employer is doing it) and maybe I'm not understanding how iOS does data separation, but it just feels like there's not enough employee protections from employer seeing personal data compared to Android? Would love to learn how that works, because Apple's website is kinda vague.
