From what i ve seen at local Track,

Xray is best all round, extreme performance, does not wear out easily, Impact resistant.
Then come Hobao/Hyper 7 and 8, more classical design, but incredibly strong and parts are available everywhere for low price.
Mugen and kyosho does have there own driving style (they why there is still many kyosho user despite there somewhat old design). kyosho seem to break easier than other brands...
