I've got about 6 years operational experience with Redis. I would not use it for a queue. I struggle to consider using it as a data store these days as well with other options on the table. But that's a whole new thread so I'm not going into details here.
If you want a queue, get a queue.
If you want a relational database, get a relational database.
If you want a key-value store, get a key-value store.

Don't cross the streams.
