I compared the PX (via aptX HD codec) and the Sony WH-1000XM2 (via LDAC) over the past week and they both have their pros and cons, but in the end I like the PX much more for one simple reason: soundquality.
The Sonys weren't bad sounding, but just boring.
I mostly listen to electronic music, Minmal, Deep House, Ambient, but also a bit of Jazz and a lot of oldschool HipHop and the PX where much more livley, present sounding and had more punch.
I also like the more compact and premium design of the PX and they fit perfectly over my ears.
They are perfect for acivities, because the footprint of the cups around the ears is not so big which makes them less sweaty.
The Sonys are more bulky and use more plastic materials, but I thought the design was very sleek too and they were lighter and foldable and came with the better bag.
Another pro of the PX is the comfort of auto-playback, -pause and -standby with the proximity sensor.
I love this feature, it truly feels next-gen and makes controling the Sony via the touchpad earcups feel weird, clumsy and dated, like in an old sci-fi movie.
One big plus for the Sonys is the ANC, which is -I have to admit- much better then on the PX.
Not only does the Sonys suppress noises better (tested while lawnmowing today
), it also has a lower noise floor.
With ANC activated and no music playing, the Sonys are almost completely quiet, while the PX have a constant (but low) acoustic noise.
I hope B&W can improve the ANC further via FW updates.

I also have a question regarding aptX HD:
Does aptX HD automatically change the samplerate/bitdepth to match source or is it fixed?
In Android Oreo developer settings it always defaults to 24bit/48kHz, even when playing back 16bit/44.1kHz content.
