If you plan on programming it yourself you may find the Nevo remotes and software to be more accessible even though nevo and URC both have installer-only restrictions. That may be all the info you need. In the end they will both be able to adeptly control your equipment and there are certainly pros and cons along the way. Here's just a few:
- More accessible product & programming software - adv. Nevo
- Better color screen - adv. 980
- Less expensive - adv. Q50 (remote + Zwave vs 980 + RF)
- Ultimate power - adv URC (980 has more options like vbova mentions and MSC400 processor is much more powerful if you add that)
