I actually met with the Sergiy as well a few months back! Super cool guy. I also highly recommend quilter - thought it was super cool (not paid haha).
Quilter doesn't have the best support for impedance matched traces. We do 90Ω on a 4 layer board and Bob Smith termination which has some pretty goofy design requirements.
