I use both 4 and 5 strings, I find it easier to play on 4 strings because the neck is a bit thinner and faster.

the 5 strings are neat too, you can play them 'lazy' style, because you don't need to go down the frets for lower tones. plus you'll have a lot more low end, which is good.

and not only for gay nu-metal, a whole shitload of bands play with 5 strings.

just don't drop A tune it and slap like a moron, and you'll be fine.
