Definitely prefer a phone with a proper jack over one without. I know there's adapters, but that's taking up the only available slot, and I don't appreciate that at all.
I've been using my Bluetooth buds for a couple of moths now, and while loving them, I don't want to be limited to only Bluetooth for my audio, be for unfortunate cases when the buds don't work, or for something as simple as having a great wired pair at hand.
I have both options, but my wired earbuds definitely sound better. I've even found that I get better wifi range with the wired ones plugged in too. My phone only has USB-C now so I just keep the little USB-C to 3.5mm audio adapter attached to my headphone cord
