What are the strongest rugby union competitions in the world...I have identified the following...

Super 14 - I assume to be the strongest as its the strongest clubs from aus/nz/sa,
(query - do the aus and nz teams draw talent from South Pacific Islands..I've spotted 1 or 2 players, not too many?)

British competion - Does this competition incl. clubs from Eng, Ire, Scot and Wales??

French - The French seem to have huge depth of talent, and it seems that Argentinians often play in the French setup...and Argentina I also rate as hugely talented upcoming power in rugby.

And then obviously the local setups in aus, nz and sa...last season and this next season after super 14 should prove that currie cup getting much more competitive and much stronger...however most of the talent is homegrown.
