The conclusion on sound quality at the bottom of your link:
"when playing an uncompressed 16-bit audio file on the iPhone 6s, the dynamic range dropped from 99.1 dB at the headphone jack to 97.3 dB at the adapter. Though keep in mind, this slightly lower measurement is still higher than the theoretical maximum you get from a compact disc (which is 96 dB). So, is it a difference you are likely to notice? If you sit in a quiet room with a really, really good pair of headphones … and you’re a canine, the answer is: maybe."
In the case of the iPhone 7 the laptop bag is my pocket which has much more limited space and a hard connector getting situated in the wrong spot could end up being uncomfortable until readjusted. Additionally it is not just a wiring adapter. The Lighting to 3.5mm adapter actually contains a DAC and ADC inside of it which unfortunately causes the audio quality to suffer slightly compared to a higher quality dedicated DAC/ADC solution inside the phone.
