It'll depend on what you want to do with it.
It'll have a ton of get up and go, just like Eric/Hotrod150 says. That said, I know of a guy who upgraded from his RV-4 and regretted it -- ended up selling the Rocket and buying another RV-4.
Here was his deal -- he flies a lot with a bunch of RV owners locally (including my RV-4 partner). They do a lot of formation work, and occasionally rat-race and dogfight. In formation aerobatics, and hard turns in the rat-racing and dogfighting, the shorter wing and higher weight of the Rocket led him to bleed so much energy that he was worse off than his buddies in straight RVs, even though he had the power advantage. You could argue that he could have solved that by flying the airplane differently, but he just wasn't happy. Got rid of it and got another -4.
Now, that's a pretty particular niche. I'd LOVE to go for a Harmon or F-1 Rocket, but the money rules it out, and my rat-racing (former fighter pilot) airplane partner would object anyway. If you can find one, the F-1 Rocket with the Evo wing probably would be the best of all worlds.
By the way, the RV TW airplanes, at least those with the reinforced firewall/gear attach points, do real well on good grass, and ok (not great, but ok) on less than pristine stuff. In the pacific northwest, my RV has been into Stuart West, Stuart East, Tieton, Easton, Bandera, Stehekin, and our cabin airstrip. With the exception of Stuart West (one way, short), these are all pretty benign airstrips.
That said, we've got a rough stretch on our cabin airstrip -- the RV gear really flex a lot on that patch (partner came in to visit, decided the rough patch was ok, so I got to see it from the outside). I don't use that stretch in the RV, only in my 170 (running 7's), and my neighbors with nose-draggers don't use it either.
So, roughness wise, you could probably take this thing anywhere you could take a 172. You'll get out in a lot less distance, and about the same getting in.
Hope this helps,

Besides, always know which way your aeroplane is pointed.
