The AYC is reliable if looked after, and gives it better road holding as it distributes the torque to the grippiest wheels. IIRC, the RS only comes in white, has cr4p wheels, cr4p seats, no AYC, no air con and no sound deadening. As an every day car I reckon it would become wearisome pretty bloody quickly. E5 or E6 GSR would be the best bet; IMO, E5 for looks or E6 for performance.
