Tokyo DisneySea has two roller-coasters, a Togo kid's coaster (in place of a Vekoma roller-skater) and an odd Intamin looping coaster that's a sort of clone of another in Disneyland Paris.
I think it's worth keeping in mind that you can generalise brands like car-makers to a certain point (one's rough, one's smooth, one's reliable) but the reality is far more complex. With any project this large, this complicated and subject to differing local regulations (both government and company) means that every single install is unique. Let's just say that again:
Every. Single. Install. Is. Unique.
There may be common threads in design, parts and components or track layout, but even in Australia, off the shelf models of some notable rides differ greatly to their overseas counterparts for various reasons. Added to this, these days many of the same ride companies rely on the same third parties like Stengel or Ride Centreline to do a range of engineering, G-force calculations and even ride design. In which case, it really comes down to the client, the brief, budget and who's behind the project, and if that all comes together in harmony. And that human variable alone is enough to suggest that simply looking at stats and going "they suck but these guys rule" is at best causation through correlation.
