I have WProcket, Breeze still needed?

I have WProcket. Do I still need Breeze and Varnish? If yes, why? Would that be any conflict?

I Think this article Cloudways Blog is helpful. Please read this…

You do not need the Breeze plugin installed if using WP Rocket, WP Rocket detects that you are on Cloudways and that Varnish is enabled and will clear Varnish cache when you clear caches. We use it extensively on 100+ websites. Works really well.
