BLE device New Development

I have been tasked to find a new BLE device and implement it on 32 bit PIC processor. 
I have a decision to make between 3 device namely RN 4020, WINC3400, RN4871. Wondering if any one of the experts in BLE could help and share some information and experience and support on the devices. Right off, the microchip website does say that RN4020, SIG will have deprecate ver 4.1 but the device is readily available in Digikey.  
https://www.microchip.com/wwwproducts/en/RN4020
 
WINC3400 is not has 20 week lead times from digikey and sounds like sourcing could be an issue. The device seems like an excellent choice otherwise. Does anyone have any experience?
 
RN4871 also seems like a spectacular choice. 
 
Once the code for one of these devices is written, can it be easily used to interface to other modules?
How have peoples experience been with any of these devices?.

I haven't used any of the ones you've listed, but I've used the RN4870, and it was a buggy mess.  I was using it as a Central.

I used the RN4678. It works well enough.
So my predecessor seem to have some issues with it but I didn’t see it after I recoded.
The text protocols Or a little time consuming to code because they are not consistent. Which means each one has to be coded separately along with all that’s possible responses. So it’s a little tedious. I hadn’t tried the binary modules so I do not know if they are any better.
