The pluses are the latest and greatest in the current scanning technology over the previous classic "T" models. Also, continuous improvement with input from the end user in firmware updates.
The list is huge, take a look at the WIKI:
BCD996XT - The RadioReference Wiki
The bold type will point out the changes from the classic "T" model.
The down side, if your in a metro area with lot's of RF all near your antenna, you may need to use the attenuator or IFX (Intermediate Frequency eXchange) to get around some of the overloading or interference. You can also purchase aftermarket filters for the offending bandwidth in extreme cases.
You also need to do some homework and see what system types are around you. What type of trunked systems are nearby? The 996XT supports Motorola, EDACS, LTR (regular only), and P25 trunked and single site systems. It will not decode ProVoice, OpenSky, or other proprietary voice system types (nor will any other scanner on the market).
