In NL the better player usually has a much bigger advantage over the worse player than in limit. I think it is reasonable then when you start off learning and getting used to the game that limit might be a better choice.

However, limit players need considerable preparation to be able to convert to NL. Reads and making tough folds is much more crucial in NL. When the betting is hot and heavy in NL the hands are usually much nearer to the nuts than when the betting is hot and heavy in limit. Also the really juicy live ones that think they are Gus Hansen don't last nearly as long at NL so you won't see quite as many total live ones.

If you want to start out immediately with NL then I don't see any problem reading the section of Getting Started in Hold em and playing the short stack system. This will keep you from bleeding chips too fast and will allow you to see how things are done.
