They are better than everything else. See below. Also, Purism is the only company officially saying they want to change the industry for the better and won’t stop even after they receive RYF certification.
Meltdown and Spectre

Meltdown (security vulnerability)
Meltdown is one of the two original speculative execution CPU vulnerabilities (the other being Spectre). Meltdown affects Intel x86 microprocessors, IBM Power microprocessors, and some ARM-based microprocessors. It allows a rogue process to read all memory, even when it is not authorized to do so. Meltdown affects a wide range of systems. At the time of disclosure (2018), this included all devices running any but the most recent and patched versions of iOS, Linux, macOS, or Windows.

Vulnerability is in the proprietary CPU microcode, below the level of Libreboot, and cannot be fixed. I do not recommend to use such laptops or advise them to others.
