My 2¢ -
The only way to know whether the SDS100 works better than the 436 FOR YOU, is to try them both. It’s just not possible to devine the answer to this question in internet forums, there are too many variables that affect real-world performance. Sorry, that is not likely something you wanted to hear.
Also, earlier someone recommended Whistler products and touted their EZ-Scan program software as being easier than Uniden’s Sentinel. That is just someone’s opionion, like nearly everything else stated here on Radioreference. My opinion is that EZ-Scan is the single WORST piece of scanning software I’ve ever used, and I’ve used many. Which isn’t to say Sentinel is great. It’s not. But I think it is better than Whistler’s software, and Whistler has yet to release a scanner model that promises improved performance on simulcast systems. In other words, a radio that competes with the SDS100.
My final point is that in order to use ANY of these modern scanners to their full potential a person really needs to invest, not just money in the radio, but also the time required to learn how to use it and program it properly. A person telling “programming horror stories” is just a person who is still learning the software. All of the software programs out there, whether it’s Sentinel or EZ-Scan or Butel or Freescan or whatever, are fully capable of doing the job you want them to do. All it takes is an investment of time and effort to learn them, as none of them are very intuitive or easy. Without that effort your fancy new scanner will be little more than an expensive paper weight.
