Without any details door #2 sounds better for the reasons you give.
That assumes I would like both ships, both cruise itineraries, and the place I will be touring in between. A consideration for me, which might not apply to you, is the total length of the vacation. I personally do not enjoy vacations that are too long. So, if we are talking about two 10 or more day cruises with 7 days in between, then I would not do that.
The nice thing about this decision is you either choice is good!
