The Librem 5 has been delayed for years and the behaviour of the company is kind of sketchy, however going by Purism's videos the software is pretty good and getting better rapidly (and they upstream their changes back to Gnome).
The PinePhone has shipped to some developers and the company has a history of actually making functional products, but the software is still a WIP, and Pine64's products are cheap (which is great for many people, but I would rather have a $400 phone than a <$150 phone, especially given that these ones won't suffer from software obsolescence).
I can't wait for these things to become at least somewhat functional - I personally will be buying one as soon as they get phone calling, SMS, and a web browser (the Librem has them, and other Gnome applications, but it's still in preorder).
