Hi I've got both installed but as I did everything at once I cannot say the difference with or without braided brake lines or sintered pads. On the other hand I am very pleased with the result. In fact you can stop pretty well using index finger only, two fingers is perfect.
If you can afford it change lines (Goodrich I have used) and pads and you will be happy.
Now, as Kev mentioned fork dive is something to consider also. I have Hyperpro springs, which definitely help.
The KTM enduro 690 is a fine bike but if I have to choose again I will take the Yammy. There is something in it.

dunno
Try you will be surprised with the result.
