the Harmony remotes are easy to set-up
Harmony support is unparalleled
when it comes to use
A) built for easy activity based operation (sit down and press the watch TV button)
B) if something does go wrong there is the HELP button that guides you into getting things back on track
c) the LCD lets you add more functions (and you can call them what you want)
d) a program guide on the remote so users can pick to watch press the name of the show and it will change to that channel(on some models it comes with it and on others it is optional )

Also (Take it this way) the more a remote is good the more traffic it gets and eventually it gets its own forum (either a remote or a line of remotes). Harmony has a very popular forum, the Sunwave maybe a couple of threads in the general forum.
