Imo you should
always mix in a separate, preferably clear, cup. For one it helps you see what your mixes always look like and get to know the proper consistencies better. I use a cheap synthetic brush to grab some paint from the
GW pot and place it into the cup, then I add Liquitex Airbrush Medium and stir to see if I have a thin enough mix. If not I add more
AB Medium. When it's right I pour it into (charge) the airbrush and get to work.

Yeah agreed, the mediums are really your best bet. Golden or Liquitex are both fine... they don't evaporate as fast as Windex or Alcohol so you can work longer / easier, with less difficulty. I do still use an alcohol / distilled water mix to clean my
AB though.
