I went with Spektrum when I got in the hobby a few years ago. Not because I thought it was the best radio...but because most of the people at the club I joined owned either JR or Spektrum, so I knew I would have help with learning to use it.
After buying it...I learned of a feature (that as far as I know) only Spektrum has called Model Match. This feature makes it impossible for you to select the wrong model. Basically, when you bind your radio and receiver, it will only work if you have the correct model selected that was bound to that particular receiver. If you accidentally select the wrong model...it will not work at all. Great safety feature if you ask me and worth its weight in gold because of it.
I never realized how important it was until I bought another brand of radio to run my tmaxx, rock crawler and boats with. I forgot it wasnt model match and I did not have the correct model selected before I turned on the model's RX. Almost stripped a throttle servo because of it or I wouldnt have even known.
I realize we are always supposed to do "pre run checks" and one should notice not being on the right model...but sometimes even the most cautious person can forget. And having that extra safety measure to be sure you have the correct model selected in memory can save you some money and possibly an injury.
Also, you may not always know you are on the wrong model IF all servo directions are the same for lets say...2 planes. And when you do your check it appears that all the surfaces are going in the right direction...BUT the expo and rates are extremely different. You could end up taking off with a model that has way too high of rates or low of expo for you to be able to handle...thus causing a crash. Model Match is almost the greatest thing invented since sliced bread! lol
just my .02's again.
