Well I have had both. I got the Pro-106 first, and a month after I got fed up with it, and sold it. Got myself a 396XT instead. It is a much better radio for the size.
The 106 is a freaking brick, and under my shirt it looks like I'm wearing a colostomy bag!
The only 1 custom search range really ticked me off, and the inter mod was so severe that I operated it mostly with the global attenuator on.
The radio never came with a programming cable, I had to spend a pretty penny for the cable and software. The 396 came with a cable, and I use freescan with it. Pretty impressive program for free!
On the City of Regina, and PPSTN, like to organize agencies to their own number, so I can shut them off and turn them on when needed. With only 20 available per V-folder on the 106, I found myself combining agencies together to make things fit.
I just love the number tag option on the 396, getting to a specific talk group on the uniden was much faster.
The audio quality I found to be the same.
I could go on and on, but uniden wins hands down IMHO!
