I have a Royale, a Premier and two Maxi Riders, all great car seats! You can't go wrong with any of the Safe N Sound car seats. MantaRay is right, the Maxi Rider will get much more use because you can use them from 6 months of age to 7 years (8 - 25kg). Most other car seats can be used from 0 - 4 years.

Good luck
