Reference question.

I'm almost done with the third season of Buffy the Vampire Slayer, and I know Angel kicks off right at the same time as season four. I'm aware there's a lot of crossover, in characters shifting between the shows if nothing else, but what I don't know is the best possible viewing order. Just going by air date doesn't seem like it'd work, since there are multi-part arcs for each show and flipping back and forth when I have everything on Netflix seems a little silly.

I found this guide, and this one - so to those who've seen both, which looks better?
