What's wrong with choices?! I think it's great that there are multiple manufactures... I hope they come out with more, deans are getting a little old.. I've ran bullet connectors and that was so easy, unfortunately I no longer have a battery like that so I run deans..

IMO this is like saying why are there so many different kind cars? Can't we just make one and mass produce it. Now How boring would that be?

Options are your friend brotha... Just buy a decent soldering iron and you're set...
