I never got ads in any of the Samsung apps, I keep hearing this but never saw it in my lifetime using Samsung phones.

Also don't know what are people's problem with Touchwiz. It's a launcher, why are people so anal about a launcher? It does what it's supposed to do and stays out of the way.

I chose Samsung because of the value it brings in software, particularly Knox and support for app containers. Their hardware ecosystem is also quite fleshed out, although I haven't buy into it yet.

No other phone manufacturer comes close in terms of value.
