I think the article is recommending it, but only if you specifically want something that's iPhone sized, but cheaper and based on Android.

If you can tolerate a larger device the article suggests a couple of other phones instead:

Cheaper and with better camera: Huawei Honor 8

Best value (flagship camera, CPU and RAM, but still £20 cheaper than the nova): OnePlus 3

Personally (I know I'm anon, but hey!) I bought the OnePlus 2 for me, and more recently the OnePlus 3 for my wife. Both are very good phones and amazing value for money.
