Finally switch to Uverse?

I've read quite a bit about discussions regarding DSL vs Uverse on this forum and in general online.  I've had AT&T DSL for over a decade and I've never had any problems with it.  I grew up on dial up in the country, which was tremendously slow, so dial up has always seemed like super speed to me.  My connection is about 5.2 MBPS, or so, which from my understanding and research is now fairly slow.  

For at least two years, I've been getting frequent letters from AT&T suggesting I switch, as I can "save money" and get a higher speed by switching to Uverse.  I recently also switched jobs, which allows me to (eventually) work from home using a VPN service. I would be answering phone calls and it would rely 100% on my Internet connection.  I've already thought about switching to Uverse as I'm online all the time, but the job change has me thinking about it even more.. but I'm afraid.  I hear mixed reviews about the reliability of Uverse.  According to the AT&T page, I can not only get Uverse, but AT&T Fiber as well.  AT&T buried a box-like device in my front yard close to the street a year or so ago, along with the two houses next to me.  I don't know if that had anything to do with the Fiber or not.  

If it worth diving into Uverse?  Is DSL really going to be dropped by 2020, or is this just speculation?  I am leaning toward making the jump to Uverse (finally), but I am just so hesitant because I've had DSL for so long and it's always worked well.
