My partner sometimes has a website which breaks, especially when she's shopping online. Which you could consider a Good Thing. For me, the website which breaks is AliExpress. Specifically, the pictures don't load. Quad9 by default also blocks porn websites. For me, that's intentional, but YMMV.
My experience with WireGuard has been fantastic. The configuration is straightforward (way less complex than OpenVPN), wg-quick(8) is ace, the macOS and Android UIs work very well. The performance is great (both throughput and latency, even of the userspace ports). You only need very minimal, basic knowledge about networking and public key cryptography.
I got some minor complaints. For example the VPN is gone on Android when the app gets updated, and there's no official Windows client (though I don't use Windows right now). The EdgeOS port is sometimes out-of-date but its made by a 3rd party. And, compared to ZeroTier (where I was coming from) I miss out on a nice website configuration, but I get back a CLI one.
