Given how even the "stock" Swift is quickly being declared the Far Eastern supermini driver's choice, I have no doubt whatsoever that the new GTI will meet, and even surpass the ori GTI's legend, fabian.
That said, we have to look at things in context. Back in the day, the fact that the GTI had a twin cam 16 EFi engine was already revolutionary for its time. Hotter 1.6 civics still only had twin carbs / first gen PGM-F1 Si engine. The B6 was also making waves, but there were no other 1.3 hatches worthy of comparison. Charade Gtti springs to mind immediately, but for some reason, they never caught on. Poor handling perhaps? With a sub-1 ton weight and killer handling the GTI was automatically destined for greatness.
Now, there's an incredible variety of sub-hatch / superminis featuring awesome technology (see 4WD turbo tiptronic 1.3 Daihatsu YRV of a few years back even), but none of which are worthy of being the driver's choice. Not even the Jazz, which I think is a competent, but certainly not a communicative, machine. Its not meant to be.
