It's going to be good for taking hits on urban features regardless if they are in the park or in an actual urban environment. I demo'd a Forum Contract 146 (145 lbs) which is standard issue urban board and it's fine for hitting all sorts of boxes, bars, rails and things like that so I'd imagine the Rat having the same core, camber and similar design would be similar.
Riding it around is alright on groomers and it has decent grip but you're not going to be going fast one, because the base isn't particularly fast and two, it chatters like hell and gets squirrely at speed. It's fun for butter though, because the Pop Camber (DC's new Lock and Load camber looks similar) has a nice flat spot for pressing making buttering pretty chore free.
Mind you, these apply to the Contract so might not be perfectly applicable to the Rat....
