I know your feeling!. When I changed from my 2004 Varadero to the AT, I was expecting the brakes to be 100 times better. Turns out they give the same feeling. Decent braking and enough for most situations, but a bit of a "soft" feeling, as if there was not enough bite.
And comparing to Yamaha, I tried the 2019 Tracer 900, and those brakes work! power brakes ofc, but so strong and precise, you can go from 100kmph to 10 and then bring up the back tire and do a stoppie, all with nice smooth action. At some point I'll try the braided lines and different pads to see what it does.
