Nothing bad about textile unless your only racing on the track.
I have both, and generally prefer the textile jackets - particularly for comfort and longer rides (there is of course some difference in protection between leather and textile but on the road your probably going to be dead if your at that extreme anyway, it also comes down to the specific jacket and its quality) , I would avoid synthetic leather in a jacket at all costs.
You can generally also pick up slightly heavier real leather jackets at better prices if your trying to save a buck without giving up the extra protection it provides. You won't look as 'cool'.
