I might try and start Hunter X Hunter and I'm not too sure what I'm getting into here but I'm interested and I was wondering if I should watch the 2011 version first or the 1999 version. I saw online that I should watch both and I might if I like it enough but which should I start with?

The 2011 version is just a remake of the 1999 version with two more sagas(one saga is pretty short while the other is the longest saga in HxH)

The 1999 version sometimes unnecessarily drags out a lot, much more than the 2011 version does.

The 2011 is the best, better music, storyteling, animation and voice acting. 1999 ends abruptly and misses 2 arcs. There's also 2 movies for the 2011 version also.

It's been said, but I'll echo - the 2011 one makes the 1999 run redundant. 

Cool then I will start 2011 HxH then. I looked up comparisons of the voices and I have to admit that I like the 2011 voices more, though it seems 1999 had more detail in terms of dialogue
