I think one of the biggest benefits is the set it and forget it. Unless you bang it out of alignment, once you set it up, you rarely if ever, have to adjust it. Shifts quickly, you have some options on shifting, and assign additional buttons to handle other itmes , or adjust the shift levers different options. If you are a data geek, it will tell you bits of info about your shifting patterns along.
I personally like the ease of setup, lack of cables and not having to adjust cables. Probably not huge issues most of the time, but those are my top 3.

you should learn to embrace change, and mock it's failings every step of the way.
