Are the Islands better than owning a house?

[Toutatis]

The problem with the Islands is that they offer no functionality. I use my house as a base in between activities: I can directly teleport in front of it, it’s more quiet than Limsa, there’s a MB in front, I have a dummy in the garden, different vendors inside along with a retainer bell, fc chest and armoire and I can allow friends to use it too. The only thing missing is a dresser but my GC is at 35 gils only away. If they added similar functionality to the Island I would use it more. Atm, I only visit it once a week to set the agenda and feed the animals as there is nothing else to do there at all.
