I have tried Shetland a couple of times. The tempting of all those bonuses is very alluring but it takes a bit of effort to get them all and by then the game doesn't have all that many turns left in which to use them.
It also gives you little income and very few points. Not only that but to get the income you have to cover up squares that don't have negatives on them and if you want to get the beans resource you need even more tiles to go around it. On the other hand beans are not the best so maybe just covering them up is a better plan?
As you have pointed out though lots of the grey tiles work well on Shetland which leads me to think you want to get a longboat and go pillaging rather than whaling with this island?
As using this island is one of the few ways to get cutlery I have also tried comboing Shetland with the 4 action space that upgrades cutlery to necklaces. The concept of a necklace made out of cutlery is highly amusing but after all that effort I don't know if it was worth it.
