I take back that question because I recently got a Huion HS611, replacing my old Ugee m708 and the difference in pen pressure control and accuracy was night and day! So glad my frustration with the brush pressure/control was mostly due to a bad tablet. The Huion allows me to change the pressure how I would want it enabling me to get really clean lines. Your line work is quite inspiring and a helpful reference to learn from, hopefully I can get to that level of control soon!
