The thing I like most about it is the way it levels many aspects of RC running/racing. Power and speed is no longer something that is only achieveable by the few who know how to skim motors and condition sub-c cells correctly. Anyone can buy a cheap brushless combo and be blasting around the streets or the track just as quick as the other guy. The racing is now more focused on set-up, and the drivers driving skills. I started club racing a few years ago and everone was already using brushless motors. I ran my first heat with a tamiya dyna-run motor, and although I wasn't as fast, it made me drive smooth and neat. It was amazing that I managed to stay mid-feild simply because I wasn't crashing, whereas most people were over-powered and simply spinning wheels and sliding all over the place. I still find this is the case with a lot of drivers, whether experienced or new to the racing scene.
I think the other major benefit of brushless tech is that it is so simple to use. It's made it more appealling for new people to try RC cars etc, as they realise that they can go really fast, from word dot, and have as much fun as anyone else.
It also means that people crash a lot more, so spend more on repairs, which keeps the hobby industry economy strong!
