I visited both Tenerife and Gran Canaria ports this voyage and below is my comparison
Tenerife port is walkable, las palmas is not. You have to take bus 1 or 12 to get to old town in las palmas. It’s 1.4 euros each way and you pay on the bus . Note they give change.
Gran Canaria has a few museums - the cathedral (4euros). Go to the top by elevator in the tower(included)
And Columbus house (4 euros). Both are worth the entry fee and are really close to each other
Tenerife doesn’t have museums but the auditorium and palm gardens are close by - 10 to 15 minute walk from the port
You can walk from the ship to the port entrance in Gran Canaria but you need the shuttle in Tenerife. Get off early or it can be hours for the shuttle.
Gran Canaria has a beach -10 minutes walk and Tenerife has a public pool that is huge near the auditorium. It’s only 5 euros.
The market is excellent in Tenerife and horrible in Gran Canaria
Personally I prefer Tenerife as I like to walk, and it’s not a huge city and not as crowded as las palmas.
Hope this helps
