Caddy is increasingly popular these days too. I use both and cannot decide which I prefer.
I think most homelabbers default to Caddy and/or Traefik these days. Nginx is still around with projects like NPM (the other NPM), but Caddy and Traefik are far more capable.
DevOpsToolbox did a great video on many of the reasons why Caddy is so great (including performance) [0]. I think the only downside with Caddy right now is still how plugins work. Beyond that, however it's either Caddy or Traefik depending on my use case. Traefik is so easy to plug in and forget about and Caddy just has a ton of flexibility and ease of setup for quick solutions.
Caddy's configuration is so simple and straightforward, I love it. For sure a more comfortable experience for simple setups
