I think you were expecting the 50mm L to live up to it's reputation and it wasn't quite what you expected in terms of bokeh. You also don't have to have have a light source in the bokeh to stress out the lenses bokeh ablities, a busy background can be as bad or worse as a light source in the background. To me bokeh is very important in portriats and the differance is definitely worth it if you are being paid for a wedding. It's a tougher call if it's just a hobby, you have to justify how much you will use it, how much it would benefit your photographs and if it's worth the price for you.
