Q Is Redis Object Cache or ezCache better for WordPress sites?

If your goal is raw backend performance with Redis, Redis Object Cache is the sharper tool.
Q Which is easier to set up for a WordPress beginner — Redis Object Cache or ezCache?

Q Can you switch from Redis Object Cache to ezCache (or the other way) without losing data?
Yes, you can switch between them without losing your WordPress content or settings, because both plugins only cache temporary data that regenerates automatically. When you deactivate Redis Object Cache, its cached keys are flushed, and ezCache will build fresh caches on its first page load. Your posts, pages, and user data remain untouched.
