In Houston a universal LNBF might give you a few extra stations on satellites with transponders below 11700MHz. Last time I checked there was only one channel worth watching. Look at the satellite channel lists and see if any target channels are on transponders below 11700. Most North American hobbyist go with a standard type, but it really is up to what is available. For example, in California there are no additional transponders/channels available with a universal type in my area.
The noise figures on LNBFs are usually marketing BS. The .1 and .2 figures are not real, the .3 and .4 NR are a realistic range for a good quality LNBF and the .5 - .8 range are where most off the shelf OEM LNBFs are realistically manufactured despite what is printed on the labels.
