*Does Remote Plus improve other games?*

[*Sound Of Rain]

I was thinking about buying a Wii Remote Plus but I have some questions about it first...

1) Does the Wii Remote Plus work just as good or even better than the Motion Plus?

2) Does the Wii Remote Plus improve Motion in non Motion Plus games?(Like now it can fit in the Wii Wheel so will it improve Motion in Mario Kart Wii)
