We currently have Londeck flooring, it's tough, non-slip when wet, and easy to clean. I don't personally care for the Loncoin look and it builds up crud around the circular 'coin' edges. But personal preferences vary - both are very durable utility flooring for outdoor use.
Marine deck vinyl is another option at slightly lower cost. It works fine but doesn't feel as 'refined' to me as Londeck, and it's a little harder to clean.
