I didn't set out to want to 'jump ship' on the iPhone. I am a proponent of iOS and the iPhone and have been eversince the iPhone 3G. But if I am honest, I have never really given 'Pure Android', i.e. Google's Android Experience--The Nexus line of phones and tablets--a true go. I am doing that now and it actually started out as an accident because I bought the Nexus phone that I am currently using in order to support some software that I was potentially going to need for some work. Well, the work fell through, but I still have the device.
What initially brought me to giving Nexus and Google's Assistant (Google's AI), which feature set I happen to use quite a lot in iOS through Siri, was the fact that the Google AI is able to do a lot more for the user than Siri can currently do for iOS users. I've heard a lot of people say that they don't use the Assistants all that much on either side of the OS fences, but I do and their penetration into our daily lives is only going to increase as the technology becomes more and more integrated into the products and services that we use everyday. Google has let their AI out of the bag quite a bit more than Apple has let out the leash on Siri. How this translates for me is in the simple helpfulness of everyday tasks. Google Now is able to help me, while Siri politely tells me, "I'm sorry Sean, I cannot do that". When has this happened? When I am asking Siri to turn down the volume on my Bluetooth connected speaker system while I am washing dishes in the kitchen. Siri cannot help me with this, but on Google's AI with a Nexus phone, the assistant is happy to oblige (having access to the device's settings controls). This is something that is off-limits for Siri. Siri can create or turn off alarms, and Bluetooth but that's about it when it comes to asking for help with device settings. Google's AI also has contextual awareness when conversing with you. This is huge. It means that when you ask an initial question with "Ok Google" and then once you have the answer, you follow up with another question about the subject matter in the question, you will not have to reiterate the subject matter in the phrasing of the second question---Google will understand to what you are referring and just give you the answer. This is so much easier. Talking with Siri is sometimes similar to talking to someone with mid-stage Alzheimer's or Dementia. I'm sorry for the analogy, but once you start using Google's AI on a Nexus device, you'll quickly understand the feeling that I'm referring to here.
Pure Android operates more like a computer where you have free reign to change granular settings for individual apps and what they have 'permission' to do or access in regards to your device. With iOS you have to accept the app permissions as a whole packet when you instal the app. You cannot go back and change a permission or two to disallow this or that or accept this or that action. With Android you can change the permissions either initially by disallowing the permission request from the pop-up when the app opens for the first time or by opening the permissions list in app system settings (main phone settings under apps>*app name*>permissions) later. I'm not sure if earlier versions of Android were 'sandboxed', but I'm running Android N developer beta on my Nexus and Google says that this system is. The Nexus phones are also encrypted by default now. That's nice in my estimation. Why? Because you can leave app permissions as they are (and Be Sure and Read Them Prior to Install) and as long as you only install apps from the Google Play store (and keep 'Allow Apps from Unknown Sources' toggled "off" in Settings>Security) with high ratings, you should be secure. iOS makes it so that you don't have to think about any of this and there's something to be said for that, but it's a trade off: (Oversimplified) Plug and Play with a Choosy Assistant or Complete Control (hands on the wheel) with the attention that requires)) with an Integrated, Higher Security Clearance Assistant.
Afteryears with the former, right now I'm enjoying a prolonged test drive with the latter.
Note/Disclaimer: I am technically minded and so I love having more of hands-on approach with my technology. It's certainly not for everyone. If you are the kind of person that gets 'mad' at your devices when they will not do this or that for you then perhaps iOS is better for you on the whole. If, when something is not working like you expected it to work OR like it has 'always worked' in the past and you find that 'interesting' and then put on your 'Tech Sleuth' hat and get down to figuring it out with a kind of excitement, then maybe you would enjoy the experience of Android, which both allows you and your apps more free reign, but also 'can' require a little more of your involvement.
