I am a gadget fanatic, but I also love to maintain privacy. One problem I always see mentioned is wallet garden on iOS. I put some of my experience into the ring here. I use GrapheneOS as my daily drive for most things. This starts with no google services and ends with profiles where I can separate people and groups and install multiple of the same apps.. like signal etc.
For lots of my work, I use a samsung fold 4. It replaced my laptop, and it's convenient. With adg (remove many Samsung apps and the Facebook and microsoft bloatware) and block internet access to most apps via rethinkdns and decloudus, you get a pretty convenient yet private device. I monitor what goes in and out and block all i don't need.
My family is all into apple so I also have an iPhone (not an excuse haha, I also love some of the wallet gardened things. Like apple music, imessage (for very few people) and I love the focus setup. I know you can do a lot manually on android to get it similar, but focus modes are a killer. I also never found as great looking and working mastodon apps (and yes, I use tusky, fedilab, and a few others on android. I still prefer what ios (some paid, some free have to offer, mammoth comes to mind on the free end). To make things more private, I use adguard pro in combination with decloudus and block apple our of the device. Still get push, and all works when you add a very few domains listing on the decloudus whitelist page.
So I use 3 options (GrapheneOS what is surly the best when it comes to privacy) but also wouldn't want to miss ios or a fold.
iOS is great and if it works for you and you are happy with it, perhaps even have a mac then you can make it a great, private and secure device. Use lockdown mode is also a great way I didn't see on android yet.
