Not recommended, yet. I tried Ubuntu Touch on my Nexus 5 and it wasn't smooth experience. Its promising project, but still under developed and it just needs more time and funding if you want it to become your daily OS for phone. Support them if you can, but don't expect too much if you decide to boot it on your phone.

Oh well, don't know for your device, my guess is that it should be just fine but don't take me on that, wait for someone official for responce

Yes, I'm not talking about usability, but about having obsolete and insecure firmware due to proprietary vendor
