Toe-Up or Top-Down?: I Just Wanta Knit a Pair of Socks!

Opinions please! What are the advantages, disadvantages and such of knitting socks either toe-up or top-down? I am a newbie to sock knitting. I'd like to get off on the right foot (no pun intended), or I may develop a life-long phobia of knitting socks!

I'm going to knit Liat Gat's Quick and Easy Lounge Socks.

 I look forward to hearing from all of you sock knitters out there.

Thanks!

Happy Socks!
