Nice list. I’m loving perfmatters after using it for a few months. Just switched from using Bricks built-in lazyload to perfamtters lazyload, and PSI scores on mobile jumped from high 60s to the high 90s which is kinda wild to me.
For good managed WP hosts - I would also highly recommend Rocket.net. I think they get better performance on average compared to WP Engine, Kinsta, etc.
