I would go with a schumacher. The spares availiaility is great and they work well on carpet and even better outdoors!
Its pretty strong if you look after it, make sure you use a servo saver though because you will snap the steering arm otherwise.
There are loads of setups available for the schumachers also. as they are a British car they are very easy to get tips on them and to get them dialed for British tracks.
I can give you a good setup for one if you wanted for carpet
The Xray is also a very good car, i have a 009 as my spare car its as strong as hell too, the wishbones are solid compared to the Schumi. I couldn't get on with it because it felt really rigid.
Its all personal peferance really and how you drive the car, buy one or the other and you won't be far off a good setup
