@Robby:
The 1999 one is fine. It tells the exact same story up through Greed Island, stops having filler once they get to the OVA stuff, and while the animation is never as good as a modern show (obviously) its still fine.
It's doesn't have the chimera ant arc, but if your friend doesn't care about that and hasn't been bothered by the animation so far, then no, its totally fine. Its how I got through the series originally.
(and for the complaint about the one Hisoka fight being censored, I think it actually works BETTER with the leads having no idea how it went and being off camera. More mysterious and overpowering that way.)
Quick update on the situation with my friend and the 1999 series…. when I posted it, she was early in the pre-Hunter exam, like the quiz scene, so there was still time to stop her if there was an issue with the 1999 series. She told me she was gonna lay down to go to bed and was just gonna watch an episode or two. This was at about 11pm-midnight.
I just spoke to her and found out... the show apparently really gripped her more than expected... she watched until 4:30am. She's now in the 20s episode wise, which according to her in the 1999 series means the last thing she saw was Gon's Candle fight in the Hunter Exam lol.
She's really hooked now and has decided she's gonna finish 1999 as this is where she's started up to the end of YorkNew, and when the main 1999 series ends she will immediately jump to 2011, so she won't be watching any of the 1999 OVAs. Apparently they did not dub any of the OVAs... or at the very least, nobody's uploaded the dubbed version to any of the anime streaming sites, so her only motivation for wanting to continue the 1999 series (Being able to watch it dubbed) stops there.
So, thanks for your input guys. At the very least, you guys convinced me letting her watch the 1999 series wasn't a huge mistake and she should be able to seamlessly jump into 2011 afterwards. This isn't like a Fullmetal Alchemist 2003, or Hellsing 2001 issue where the stories are ridiculously different.
Also, fun thing... talking to her about what she's seen so far... apparently Killua's gruesome fight in the Hunter Exam? The, shall we say, heartbreaking one? Totally uncensored in the 1999 version... Interesting....
OH, that also does bring up one more question. I'm probably going to have to explain one thing to her so she isn't lost when migrating over to the 2011 show, anyone have a suggestion as to how?
From what I've been able to gather, the 1999 is more accurate to the manga in one area, and that's Kite. He's actually in the first couple of episodes unlike the 2011 Anime that changed it so that Gon meets him for the first time right before Chimera Ants..... How... should I explain this discrepency to her when we get there in the most succinct way? Again, I haven't seen the 1999 series. I know there's a difference in the two, but I'm fuzzy on exactly what it is.
