I had hundreds of tests on my WordPress sites with dedicated server and created hosting. As far as I can see, currently NGINX is a fairly stable server, rarely encounters minor errors, followed by Apache. Regarding speed, when I tested the above servers with caching support, NGINX + FastCGI Cache was not the best speed, but it was the best for Web Vital on my xetaitot.com site, a WordPress site. With WooCommerce and many images. Next is Open LiteSpeed. If you are building your own Web server, I recommend using NGINX!
