Love my Lumia 950, it works very well, does everything I need. Occasionally there's an app I wish I could use, but not enough to be a deal breaker.
Microsoft did a great job making its apps responsive and I enjoy using the same software on my laptop and phone.
I'm sure this will be an unpopular opinion but there was and still is nothing technically wrong with Windows Mobile. Sadly it looks like it won't be getting any further feature updates but the current version is still supported for quite a while yet.
