zeus and phoenix are two of the most interesting lightning wallet in my opinion.
Zeus is an example of how a bitcoin software should be developed, open in pretty every aspect and avoid central points of failure. His major defects are fubctionality, payments failures are very frequent and I experienced a lot of force closure most probably caused by disconnections. Putting a node in the phone was a cool idea but seems it need to be worked on.
Phoenix, at the opposite, works really great. It explore and push the limit of how a mobile lightning wallet should function. His major defect is the central point of failure and the "closed garden" experience.
I think in next years we will have something different, hopefully something smart and well engineered as phoenix, but open as zeus.
