Seabourn or Silversea to Alaska???

[TylerRose]

We have sailed to Alaska several times in the past with HAL and was a favorite--- but ten years have past and we no longer cruise HAL.
I am torn between 2 voyages- and both are honestly different enough that if I had the time, they could follow each other with minimal overlap. I prefer the voyage specifics on Seabourn- but have concerns over state of Odyssey. (She will leave Seabourn several weeks later).
On the other end... there is Silver Muse. A very different itinerary- but a far newer and modern ship. I would appreciate an advice you can offer. Thanks in advance. 
These are the two trips I am trying to finalize:

 

SB Odyssey:  Jun 28, 2024 for your 14-Day Alaska Glaciers, Fjords & Inside Passage.
SS Silver Muse  June 20, 2024 Seward-Vancouver-Seward (BTB)

an update... After being assured by travel agent and SB on consistent maintenance of Odyssey, I went ahead and booked it for July 12-26. The itinerary escapes the standard port calls and experiencing Alaska is more important to me for this trip than the newer ship and all its bells and whistles.
