I can't make the same comparison as I've never owned a URC remote, but I've been very happy with my Harmony One. The H1 is much better built than its predecessor the 880 (the buttons were the issue) and I like the shape. Regardless of which universal remote you use I think they are the best accessory you can buy because they eliminate most if not all of the frustration of using a home theater.
One note: I really enjoy the H1 with the oppo BDP-83. I've made every connection possible on the oppo and the Harmony allows me to set up multiple Activities with a variety of inputs on the 990. Probably not a unique feature but it sure is handy. Enjoy your new remote!
I bought an 880 and gave it a try but hated it because the buttons were all in line and level. Sold it to a friend that liked it. That's why I was hesitant about the H1 but it is a far superior remote to the 880.
