Since many packages give you the choice to pick a single TLS library to support, I am curious which one is the most popular among Gentoo users.

Most info on this I could find online is either horribly outdated or just runs down a basic list of features. If you have specific reasons for picking one of them, please share them down below. Thanks!
Note that I chose not to include implementations such as wolfSSL/LibreSSL/mbedTLS, as I don't think they are comparable with the other three in the current GNU/Linux ecosystem.
