Coming from the Mini world prior to my GTI, I would say that it is all about what you want out of the car. I owned both a R50 first gen Mini and a R56 mini. Both cars were a blast in the corners and were quick, but not what I would say "fast". My MK7 GTI handles well, but not the same. But, it is much faster and really rewards good driving technique. GTI is a great GT style hatch with a high ceiling. The Mini is a fast handling hot hatch with many maintenance issues, depending on generation and model.
Hope this helps!
