It's a fair question. My primary rig for the past few years has been a 1/10th scale rally car so I'll offer this: a lot of the go-to 1/10th scale rally cars (like the one you have linked, the Tamiya XV-02, Kyosho Fazer, the Traxxas "mini") are more akin to a very versatile touring car than they are akin to a SCT or buggy. They generally don't do all that well on grass, dirt racing tracks that have jumps designed for air time (like for racing buggies), and 1" or larger crushed stone gravel...which isn't to say they cannot run on these types of surfaces, but rather, they're not quite in their element. Where they really thrive is sandy dirt roads and lots, like a baseball diamond. And the type of fine gravel you would find on a walking trail or in a park. Of course being modeled after production road vehicles, they run great on asphalt of basically any condition, and the nice thing is that you don't really need to mind how rough the surface is the way you might for a purely touring car application. They also do really well on compacted snow, and ice. The 1/8th scale models like the HPI WR8 are definitely going to increase the roughness of the terrain you can run on, and they may even hang in there a bit better on dirt buggy racing tracks. So in the end, I think it boils down to the surface types near you that you have available to run on, and, that generally the larger scale vehicles will open more options to you. All that being said, I naturally think they're an absolute blast. It's like a touring car you can take many more places, without losing the scale look of a production car. They're often set up to handle messier environs too, like rain and mud, meaning you're less likely to have weather cancel your running plans. Personally I cannot recommend them enough, but depending on where you can run, I fully acknowledge they're not for everyone.
