Let me steer you in the right direction so you can study a bit more
Yes the Apple chips are very powerful on paper but are spinning their nuts off in neutral due to OS limitations your barely getting mutli tasking let alone other functionality that should come with such raw processing power that is simply bragging rights most of the time and only emerges to show some strengths in benchmarks mostly and other than a few games or apps, IRL for most its irrelevant.
I agree Apple has strong polices on privacy but there is nothing to disprove Samsung is not equally safe, I think you are getting mixed up with Google activities that are the sporing ground of comments for the tin hat brigade, that both IOS and Android are vulnerable too, maybe at differing rates of leaks. As we can see even on MR Apple is only safe with their native apps and items on their servers anything else carries a risk even from the App store. Interestingly Samsung Knox and the secure area provided on Samsung phones is a great safer area for extra sensitive data and dual apps etc.
Apple Eco is not consistent as you may think and the obvious one is you must have an IPhone to have an AW not a LTE Ipad and an LTE watch combo will not work as you cannot update your AW but I am sure their are many other trivial inconsistencies that are inconsequential. The key points of Apple ECO advantage are long gone and we are down to simply niceties and preferences now and Samsung with MS are expanding in areas Apple are lagging in.
Apple released many flawed products that have taken class actions to resolve and years of heartache for many owners. The major vulnerability of the 1st Fold was fixed before any of the public got to buy them. No good reviewers note any differences in build quality of Samsung Flagships vs Apple those days are long gone along with available screen area comments. Although I am sure some will have fun with the plastic rear of the smaller Note20, but that's not quality construction its just less premium material.
Yes Apple do support their OS updates for 5 years but we have seen how they treated some customers and again taken legal action to resolve this. I agree its a good point but it's not like your Samsung phone stops working on the 25th month LOL and most receive security updates for another year or 2 in some cases.
As for support many seem not to realize that millions of Apple owners who pay the same prices or more than US/UK/AUS/ETC and do not get the same level of support or warranty. Many countries all you get is a lemon policy 1 year mail in and 90 days phone support. Forget about we like all our customers to be satisfied line and you can return it in 14 days or pop down the road and exchange it, nope nothing for those good Apple customers worldwide.
Yes there are differences but it's largely personal preferences centered around OS or for many entrapment due to staged ECO devices/purchases. Either OEM's flagship devices are good phones just embrace the differences as it's always good to have choices
