nRF5_SDK is freedom 
 with NCS you're a slave. You do as you're told.

Let me clarify, the idea that SDK is deprecated has been suggested in Webinars about NCS, so it comes from Nordic. Of course, SDK will continue to receive corrections, but not any new features, that is my understanding. For an existing product, there may be no reason to switch. 
 For a new product beyond BLE connectivity (IP connectivity, Thread, Zigbee, CHIP ...) I would really recommend to switch. 
 Here is why I switch to NCS for teaching, and this experience might convince you: My aim was to build a toy light control system with LWM2M connectivity for my students. SDK as NCS integrate OpenThread, but that is really where things get messy as one would have to port a LWM2M client to work with the openthread IP API. It's possible, but why do it when you get this combination in NCS for free?! 
 In NCS/Zephyr, there is a much better chance to have third party software components integrated and it is in fact easy to get the LWM2M demos running on Nrf52833 and Nrf52840 with OpenThread and the Zephyr IP stack. No line of code had to be adapted, only you have to configure the compilation to make it work. And that is the great thing about NCS, there are not only good APIs for IP, with KConfig you can plug different implementations of different platforms together and it works. True modular software! 
 I agree though that NCS/Zephyr has a steep learning curve and that you have to understand concepts that just would not occur with SDK, notably KConfig and DeviceTree. On the other hand, for an embedded software engineer who might touch embedded Linux as well, learning at least about DeviceTree is a very useful thing to do. That does take time so be prepared for it.
