IOS vs ANDROID farm

Android is bad

stick to physical android devices newer ones as they have more support available for many other softwares, apps and programs you will need for automation. cloners, automation scripts,

use 4g proxies to rotate ip address to limit tracking and verification
use phone mirroring software to control from pc

hire Virtual Assistants to scale the operation

If you're planning something long term, I'd prioritize reliability and maintenance over which platform is easier to spoof. Android may be more flexible, but fully automated IG/Threads setups can become fragile when platform detection and API changes are involved. I'd test a small setup first before investing heavily in hardware or building your own panel.

If you can get iOS, there is no questions iOS is more trusted.
