I was in such a hurry to get to England, that I chose Iceland over Greenland because it had a much shorter layover. Only ended up spending 24 hours in England, but did get to walk the streets of the country I love so much.

Were I to do it again, I'd plan for multi-day stayovers in each country, and add Greenland to the list. I never even visited a castle while in Birmingham, England or taken a bite of fish and chips. Reason enough to return though! :)
