I've had 920, 930 and I'm now using a 950 as my main phone: The hardware is superb, and I really like the OS (running Insider Preview Slow Ring). There has been a steady stream of Windows 10 Mobile Insider Preview updates throughout the last year, bringing both new features and stability. In user interaction and interface consistency it is now much closer to iOS (or what iOS tries to be) than Android is.

That being said, it is pretty obvious it is a minuscule platform; apps are often lagging behind their iOS/Android counterparts, and there are some obvious ones missing (like Snapchat and Pokemon Go).

It is kind of sad really; I think it would be healthy with more than two major players, and Windows 10 users will probably feel quite at home in Windows 10 Mobile.

I tried using it for a year. Though the UI was polished, lack of apps was a big problem. For example, What's App Chrome WebApp support wasn't released for WP when the feature was launched. Even Audible and Kindle apps (considering these are from a major company like Amazon) on WP felt inferior to their Android counterparts. So just ended up buying an Android device around a year ago.

I have a Lumina 950 as a “second phone” for use with a local SIM when I travel, and honestly I love it.

I use it. I would rate it equally as high as the iPhone minus all the apps and apple craziness. And much better than android which I don't care for. I plan on getting the flagship 950xl Lumia when this 930 im on now breaks, if it ever does.
