Use with wp-lcache?

Couple questions when to use this plugin. I host on pantheon.

1. Would you use this for membership sites? Majority of users are logged in or just use wp-lcache. Or use both?
2. Redis, Advanced Page Cache, and WP Cache. Is there a time to use all three, just two, or just one?

Trying to wrap my mind around this. I’m hosting both membership sites and regular non-member sites. A few sites already using Redis.

Thanks
