Two Jackery 5000 base Units plus smart switch vs....

while i'm sure I'm overthinking things (i tend to get this way with amazing deals on the table), I'm thinking of adding to an existing order I placed and curious if others have use cases or scenarios they have thought of or considered for one over the other....

Jackery 5000 base unit plus smart switch and two solar panels (already ordered)

considering adding either:
(1) or (2) Battery 5000 Plus units
Or

(1) additional Jackery 5000 base unit since I can also plug this into the smart transfer switch.

Appreciate your thoughts and welcome to help me overthink this a bit. Value for the money and possible future configuration/expandability is something i'm also considering. Thanks!
