Personally I find the Sharks one unimaginative and boring.
Chevrons, hoops, Vs and to a lesser extent stripes have been done to death, I think it's good for some clubs to be looking for some new modest designs, designs that have never been done before (or are rarely used) but aren't obnoxiously ugly either.
Personally my favorite of those three designs is the Tigers one (though it is by no means one of my all time favorites) because it is trying to be different without over doing it like the Eels on does.
All the best jerseys are the ones which were good looking and individual in their time, besides the competition would be a lot more boring if every club wore variations of the same four designs.
