Is the iPhone 6s Plus still good in October 2017?

The reason I ask is because I currently have a nexus 6p but the battery is horrible! So I want a different phone and my girlfriend has kind of persuaded me to get an iPhone. But I can't afford a 7/7 plus plus, or 8/8 plus so that is why I'm looking at the 6s plus. I also have a MacBook so I know that if I get an iPhone It will work good with it.

The iPhone 6S is still a very good phone--lots of folks continue to use them without any problem. And any iPhone should work well with a MacBook.

Get the Iphone SE

Yea its fine. Should be supported (iOS-wise) for another 2 years at least.

The 6 is still good and still overrated. You don't see the real issue here don't you? My Girlfriend told me to get an Apple therefore I must get an Apple. Damn.
