What is the best type of ink to use?

I have already asked but I am asking again and adding on to my question because some stodgy bag got on my case so I am clearing up my question.
"I am considering dabbling in tattooing and would just like to know what the best ink is out there. Every site claims theirs is the best but I would like to know from people who actually use the inks."
By dabbling I mean just a kit and some practice skins (Not people Miss Poopy Pants). I don't care to do anything on people unless it is myself. I have several tattoos and just wonder what it is like on the other end of the gun and if I do something I always want the best products to work with.
