A Universal LNBF lets you scan a larger freq. range but cant be used with a satellite meter. A standard LNBF can be used with a meter. I would stick with a standard LNBF unless you get a really good quality universal LNBF like the Invacom.
There are some Great channels that you will only get using a universal..... Like Cubavision (Pas 9) (loads of Baseball and music)
