Fingerings for e6

I was looking through different ways of playing e6 and found this chart, and i was just wondering if there are any downsides to playing it in the sixth way seeing as it's by far the simplest one and at least when I play it in tune in some cases more than the other options. Also it's not listed as basic though I'm not really sure what that means. Basically what I'm trying to ask is can I use it?
