The Hong Kong Seven Series is always the grand daddy of them all. This will be the 42 edition and the Seventh World Rugby Seven Series.
This series not only has the top 16 nations play but there is also the promotion/regulation groups of World Series qualifiers of 12 other nations. This year Germany, Spain, Uruguay and Hong Kong are the favorites to join the top group next year.

The USA has 2 great series in Las Vegas and Canada and now sit in 5th place chasing New Zealand. The problem looking ahead is that you have Australia on their heals.
