As this is a Ford forum I think the majority of answers will say the RS. On paper the GTi is far better but I would say go and drive both. Heart says RS, head says Pug. Both have their problems - RS : rust, Pug : usual French electrics etc. Think you would have to spend a lot of money to get the RS to keep up with the GTi.Personally wouldn't mind either.had a mk6 and they are great cars.
