I'll save you the trouble, it isn't.

I've watched 85/112 episodes of the anime, so i can say that YYH is nothing compared to HxH, it's merely a DBZ look alike, and i mean it... even though you can see some parts resembling HxH, but it's better to start with YYH and move on to HxH than the other way...

the YYH manga is probably better than the anime, you can get the few first volumes at mangareactor, but it covers less than the first 5 episodes of the anime (which means, the manga had lots' of stuff who didn't appear in the anime...)
