I started using the 6S+ 64 since Friday. My impressions compared to the 6+ I had previously:
1. Battery life is a lot better. I am not sure if it's because of iOS or the chip but it obviously last much longer compared to my 6+
2. Speed is amazing. If you play games then you would notice everything loads up so much faster and graphics are crisp. Apart from that, I also notice faster 4G/Wifi on the same network so the new LTE chip in the phone did make a huge difference.
3. On paper the weight says 20g heavier. While it seems quite substantial (we're talking about 10% increase in weight), it's negligible.
4. The 3D Touch might not be very useful at this point in time because you can still easily navigate through normal methods.
5. The extra RAM makes iOS a lot smoother and you don't need to get into Safari waiting for the page to refresh. It stays as per where you left and same behavior like the iPad Air 2 which I have.
Conclusion: Overall, it's a great buy and am happy with it

Nice Review.
Questions to your reviews
1) Could battery life be better because the 6S+ had a new battery while your 6+ had a worn out battery?
2) Both the 6+ and 6S+ supports the latest Gen 2 LTE networks. But if you say faster 4G and Wifi I wonder why?
3) Thats reasonable. 20grams is not noticeable.
4) That we need to get the hang of it before being to fully utilize it.
5) Im sure the 2GB ram makes a lot of difference. But the main issue is that Safari doesnt needs to restart every time and that makes a lot of difference to me as I really hate the refresh everytime I open safari.
Overall seems like a worthy upgrade even though the high price.
