Heck yes I'm happy with my choice! What takes away from the 'pure' experience is the bloat that VZW put on there (includes Amazon apps, Slacker radio, etc), which is actuality is not a big deal. It's not really overbearing and doesn't really get in the way. And people may actually find some of those apps useful.
However, the bloat is definitely an annoyance in general that takes up some space and requires a bit of time to sort through to disable - again, not a big deal (as some critics want us to believe). Thing is, this phone is so fast, even if you don't disable those apps, it's not really going to impact performance in terms of lag.
The Moto additions enhance functionality for most people. I think that all of them (Voice, Display, Assist, Actions) can be very useful. This is what I prefer in a phone: near-stock Android with a couple of additions IF they are truly helpful, don't get in your way, and are relatively light on resources.
Currently, the Nexus 6 is the only top of the line smartphone that has a pure Android experience and you don't hear about other 'pure' phones coming out anytime soon.
