I'm also running PeP-free mode and I'm satisfied with it. I'm thinking that maybe after initial configuration it just works so the problem is largely setup. As for keyservers even GnuPG is diminishing their role. Web Key Directory is promoted as a replacement for discovery and updates of keys. Coincidentally Enigmail will automatically fetch recipients keys using WKD when composing an email. For example kernel is using it (https://www.kernel.org/category/signatures.html#using-the-web-key-directory https://www.kernel.org/category/signatures.html#using-the-we...) so does ProtonMail.
