I have never 'upgraded', but have had X1 in MA and now in FL.
If I have voice recognition, I do not know how to use it, will have to google that later
I am a fan of X1. For me it is about being able to record more shows at once. I would have a hard time going back to not being able to watch live TV or on demand if I was recording two programs. I do not watch live TV, I o not even watch sports 'live', I delay an hour or so, so I never have to watch commercials or 'experts'
This will become real handy as 2016 approaches
