Tivo Stream Worth Keeping Once Your Have Added Premiere?

I added a Roamio Pro to my system about two months ago, previously I had a Premiere XL4 with a Stream (as well as a old Series 3). New update also included two Minis to replace cable boxes. Am still using the Premiere XL4 and Series 3 units.



Am not seeing that there is any advantage in keeping the Steam. Is there something I am not seeing that would indicate holding onto the Stream? See that there is an Ebay market for Streams.



Appreciate any and all advice.
