I suspect this will be difficult to do as most of us are only familiar with one or two competitions at best and have no real basis for judging the other ones. However I'm hoping it'll be possible to put together a league table of sorts based on things like national team depth, youth development, performances of individual players in tests measured against their records in FC, as well as anecdotal evidence (opinions of experts expressed in articles and the like)
Is it safe to assume that the Sheffield Shield is still the number one first class comp in the world? Franchise cricket in South Africa must surely be of a very high standard too?
I'm particularly interested to see how people rate County cricket and what the general consensus is re: Indian first class cricket. I know it's traditionally been an administrative shambles and a bit lacking in intensity, but on the other side of the coin, I'd have thought that with an increasingly huge cricket-loving middle class having had access to the game in the last 15 years or so, and with generation after generation of superb U/19s players having come through, their first class comp would at least be loaded with good cricketers?
