Have you actually seen an apache in the wild in the last few years? No one picks it anymore, I'm not sure why.. Well, besides the fact that nginx is now nginx-ingress-controller and we all use k8.. :/
That said, netcraft says Apache still runs almost 25% of the internet, which is no small stake: https://news.netcraft.com/archives/category/web-server-surve...
The weakness of nginx is that it can't have a dynamic module and if it's not compiled in, you need to roll your own build, which I won't do due to maintenance burden.
