Re: not using LNURL, it's mainly because I don't like hosting dynamic website code. It requires installing stuff on a server (requiring either a dedicated server or taking a risk with other stuff on the same server), breaks often in my experience, and is just not what I want to spend my time on. BIP353 looks promising because I'll just be able add a field to my existing DNS.
All that said, I haven't actually set up either LNURL or BIP353, so I could be confused about what they actually entail.
