Sophos Email (Cloud)

We just started a Reflexion trial and so far liking it.  What I noticed today was there is a Sophos Email (cloud) edition.  I'm not sure when that product was introduced.

 

I've compared the features and they mostly overlap.  I anticipate Reflexion is a more mature product.

 

Does anybody have any insight if Reflexion will be migrated to Sophos Email (cloud) down the road?  Has anybody used both services and can provide any insight if Reflexion is the more dependable solution?
