That said, IPsec is astonishingly hard to setup and diagnose. Recently I installed strongswan on my server and Windows 10 is my client. I didn't figure out how to send intermediate letsencrypt certificate to Windows 10, it wasn't accepting connections without installing intermediate certificate as trusted and I tried very hard, I'm sure that strongswan configuration is correct (I put intermediate certificates into cacerts and it works on macOS). It's especially fun with very little and cryptic information from Windows 10. Now when connection was finally established, routes were not set properly. It turned out that configuring connection via GUI was not enough, I had to change some connection property via powershell script, so client would receive routes from server. Yes, VPN isn't very easy to setup, at least for casual use. But in the end it worked and I don't see any reason to switch.
I found OpenVPN to just feel VERY VERY clunky. The clients look ugly and unpolished. Before anyone says that's superficial, I do think it shows a lack of attention to detail. Setting up the server also wasn't terribly easy (it wasn't too hard either for someone like me who's used Linux for many years).
I think most of OpenVPN's value has come from the fact that it's the last difficult of solutions to implement.
For the record, I wasn't claiming that WireGuard was this easy to setup. But I think the mentality of WireGuard is simplicity. I think it's only a matter of time before someone DOES implement a single click client/server with it.
Right now I use Algo, which is just an excellent set of scripts used to setup VPN servers. This way I don't have to use OpenVPN, and I can actually use IPSec with built-in OS clients.
Update: Also I'd like to add that WireGuard just feels like the kind of thing Apple would've implemented in their OS 10 years ago. But Apple today wouldn't. They just seem to be barely treading water in their MacOS group.
Definitely it was easier than strongswan for me. Documentation is clear, a lot of guides, AFAIK there's a single implementation, so no interoperation quirks, logging is actually useful. Client setup is a single .ovpn file which contains everything and installed using double-click or similar method. I guess that setting up a custom CA is the hardest part of setup and I just happen to work a lot with certificates, so it wasn't hard for me, everything else is as easy as any server software.

I used paid software (Viscosity) for macOS, it was quite good IMO. I used official software for iOS, it worked without any problems. I'm not really sure what's ugly about VPN client, it's systems software, it should display icon in tray and allow to connect/disconnect, that's all. I remember that my friend had issues with OpenVPN official client on Windows laptop with hibernate, but I think he just had to restart connection, not that big of an issue.

While I won't use any "single click" solutions unless I made them personally, I saw scripts which claim to install OpenVPN or IPsec automatically with absolutely minimal interaction. They had a lot of stars, so I guess they works. But if there's something that Wireguard could do better, that's good. It's still too hard for non-technical user to buy cheap VPS and setup his personal VPN with adequate security.
Check out Viscosity. I've been a user for a few years now, it’s great stuff.
The availability of ipsec, much easier to configure than openvpn, better crypto, and flexibility that none of the existing options can match, such as full IP change resilience (as long as only one end change at a time) and connection persistence.
It makes you wonder why VPN's have been so bad for so long.
It often seems to me that networking people like things to be hard and obtuse. Almost everything in networking seems more complex than it needs to be.
The whole solution just seems so elegant. It's just not at the point where I can download a GUI app and press one button to just connect. Waiting for that to happen.
