3.5 mm headphone jack is much 𝕞𝕦𝕔𝕙 𝖒𝖚𝖈𝖍 more robust than USB-C port. You can slingshot your phone by the headphone cable, and both the phone and the cable will be fine.
USB-C socket gets slightly bent and you cannot charge your phone.
It's also at the bottom of the phone, so you cannot hold it normally, while the headphone jack is at the top.
