For my 2p worth.....
I like to think I'm a kinda open minded person where tech is involved and have owned many android and iphone devices.
I do however swap to and fro like no tomorrow. However, for all my to'ing' to android I'm generally fro'ing' back to iPhones.
As a brand, Apple has it wrapped up. One company a few devices (talking iphone here) generally only 2 devices on sale at a time (currently 5s and 5c) eliminates the decision of what to buy if you are going down the Apple route.
For consumers, we can only talk in the majority, what the majority want, expect and really care about. Now Android is losing it's way slightly, in reference to the OP, what I hear in the scenario you mention is "why buy a Samsung" - not android, not a kitkat device not a google OS, but a brand. This goes back to the majority again, most people want simplicity, ease of use, minimal tech knowledge etc etc; they want to pick up a phone, open the box, charge it up and go, they don't want to know the intricacies of jailbreaks or titanium backups and modded kernels. Most don't know of evad3rs or XDA and will probably have no interest at either of those places.
Personally I believe Android will stay in the niche for some time yet, even Samsung are toying with Tizen OS, whilst it is greatly believed it is Samsung that have pushed android out to the masses via its 'S' and note lines. The world markets are so diverse, it's impossible to dominate everywhere. In the western world, we are more brand aware and style conscious (not me personally), we are the ideal Apple target audience, it's what we see and want to buy.
For instance an experience with my wife, uses her iphone 5 it fell in a mop bucket and died a death, walked in to an Apple store with the broken device, paid and excess of £45 and walks out with a refurb, however this is not what surprised her. On arrival back at home, plush the iphone in and eneters iphone password and voila everything is back the same as on her now broken iphone: apps, settings, photos, itunes purchases, everything. All this was done without her being aware or having to manually setup anything. This is what the 'majority' want.
When I had my Note 3 I had it configured to the gills with customer rom, kernel, viper audio and undervolted. This was great, a true tinkerers phone. But after a while I grew tired of maintaing everything, almost daily in some cases, and reverted back to a device that is more limited in functionality (but nothing essential and what I actually miss) but also much less hassle.
I do agree it is the Apple marketing machine that steam rolls and generates hype to the masses, but that is their success, and I'm sure that would love to be repeated by other device manufacturers such as samsung and Motorola et al.
In conclusion, just don't let it get to you. Pick a device and enjoy it you don't need acceptance from friends or salespeople. Same thing goes for Nike shoes, beats headphones, surface 3 (well perhaps not the latter

). Just do a bit of research yourself and pick what 'YOU' want and enjoy your choice, after all you can always change your mind
