If you have a big website with a lot of traffic. LiteSpeed is the choice.
I used WordOps, Cloudpanel, Hestiacp etc. But Litespeed can hand more requests. With Nginx the VPS is down but with LiteSpeed it's still available to serve clients.
Lscache also give a better grade when you test your site on https://pagespeed.web.dev/
If you still want to use Nginx, try HestiaCP or CloudPanel instead of WordOps (better support, more developers, faster update and faster new version release).
