Never intended this to turn in to a GTI v R thread this is my opinion.... I have owned a mk 7 GTI Manual (with DTUK box), a mk7 GTI DSG (never modified) and in between a S3 Manual (with DTUK box).
Biggest problem with GTI is traction.... even worse with DSG box in my opinion. I don’t know if it’s better with the diff. It sometimes surprises my how nippy the GTI is in gear.
Once up and running there is little between a R and GTI and I would say a modified GTI once up and running would really push a standard R.
However my S3 (basically a golf r) was an absolute weapon with the box installed

The driver is obviously the biggest deciding factor.
In the most basic of willy waving stats however, the 0-60.... the R is considerably faster than the GTI
