My experience with many people using Unidens, radio shacks(gre & whistler) in midland, saginaw simulcast areas with 4 towers. Additionally with peoples experiences nationwide in the forums in dealing with simulcast issues.
Agreed on comments above as no scanner is as good as what is actually used in the field of course. Even then occasionally you'll hear 911 personnel saying they can't understand what is said at times.
Well anyway, it to me is a slam dunk, the Unidens actually work in simulcast areas, whereas the people in my areas most report little or no reception with pro 651,652, ws1040,1065's and the other whistlers. Older Pro 106, 197 people weren't having a problem, short of garbled audio.
I even turned on the attenuater, less antenna etc. just don't work in many areas. Now some areas they do but must be in areas not getting signals from too many towers. The whistlers are good at pulling in all signals it can - a 'hot' front end. Although there comes a point to where they get too much signal and can't handle it.
Uniden uses firmware that helped reception in situations like this and most users in the forums say the 436HP, 536HP's do the best in simulcast areas.
I'm not a 'fanboy' of Unidens just conveying my experiences with all these models.
Here is a forum thread with a video link a fellow made who bought the high end TRX 1 scanner and lives in Saginaw's four tower simulcast system and also reported no reception. Now he took the high road and did get an expensive G4 pager that fire personnel use now. Initially its working ok but the G4 is inducing to the TRX to pickup from being close together.

Also I was requested to program your county newspapers Uniden 996XT a few months ago, comment was

"Man you are a lifesaver!!!! Everyone is super happy our scanner works again. Thanks!"
So clearly even the less expensive desktop 996XT (discontinued) works fine there, the 996P2(phase 2) is now current. The portable 325P2(phase 2) is the portable version of that. Then also the homepatrol 1(phase 1) & 2(phase 2) also work well.
