I actually picked up Sproggiwood last night. I think the quality of the UI is somewhat derived from the mobile focus. On PC this translates to a really straightforward, if slightly slower, interaction. For example, click on the magnifying glass and then click on any skill, monster, or item to examine it. That's cool. When you get status effects, you get little pill counters denoting how many turns the status last for. I am TOTALLY going to use this. The tutorial is also excellent and you are taught things at a rapid clip.
I don't know of any other RLs with similar UIs. I'd be a bit hesitant to put a similar UI in my game because some people are extremely biased against anything that looks like a mobile port.
