There's no doubt Harmony is easy to program. I have the 890 model. But you pay for that simplicity. For example, you can't have extensive macro's. With my MX900, I have a macro that deletes programs from my DVR. It takes 8 or nine clicks (list, navigate, select, delete, confirm, go back etc...)
With Harmony, I'm at the mercy of Logitech to provide an update. while that's true for URC as well, I can just learn the RF if I want to. That's what I did with on the MX900 for my Oppo until the update came out.
I also don't like the rechargeable batteries. The MX lasts for months before I have to replace it, so it's not a big deal for me.
If you like simplicity, get the Harmony. If you want more flexibility, get the URC line.
