The difference is the carrier in the paint, one being an enamel and the other being a lacquer. Lacquer paints are alright to use in most any airbrush, but care must be taken not to let any lacquer thinner get into O-rings on the airbrush since it will cause them to swell and crack eventually.
This is usually not a problem if you just spray lacquer thinner through the airbrush after a painting session. The problems occur when people try and soak the airbrush body in lacquer thinner. That is when the O-ring becomes damaged.
Lacquer thinner is used for cleanup of lacquer paints and good ventilation is a must as accumulated lacquer fumes can be very dangerous in an enclosed room.

“Wisdom is the right use of knowledge. To know is not
to be wise. Many men know a great deal, and are all the greater fools
for it. There is no fool so great a fool as a knowing fool. But to know
how to use knowledge is to have wisdom. " Charles Spurgeon
