Tried using both platforms for over two years and realized neither one really complements each other because Apple refuses to let other brands use iTunes or communicate with each other with their proprietary software and crippled Bluetooth & NFC. Also Apple hates sims and makes it harder to switch by changing the standard every two years. Apple created their own sim for the latest iPads this year. Apple is still the biggest control freak in the mobile industry.
Android & iOS mixes together like oil & vinegar for me. You are better off using Mac + Android or Android with certain strengths + Android with certain strengths if you prefer dual wielding phones. Apple wants us to only use their products. I prefer Google's services anyway but the great thing of iOS is you can use Microsoft and Google apps/services. You will never be out of each other's ecosystem by using iPhone while still being offered Apple's own exclusives. I still hate iOS' linearity which makes me prefer Android.
My preferred combination is Android phone + Android phone + PC. No tablets. Both Androids have to be different enough to complement each other's weaknesses. If I want gaming, I will stick to a console or handheld.
OP, see how it goes for you after awhile when it comes down for you to only CHOOSE ONE platform. Been there. Done that. I will stick to Android for now on.
