Husqvarna dealer from GA Onan18 says

Between the 385 and 390 I would pick the 385 all day every day. The timing numbers and port shapes were almost perfect from the factory because it was designed from day one to be what it was. The 390 was more of an afterthought "We have to get in the 90cc class to compete with the MS 660" so it is essentially a factory big bore and they had to compromise on the port shapes to make room for the larger piston. Also, while 1mm does not sound like much, the 390 piston is MUCH HEAVIER than the 385 piston. As a result the 390 is known for killing cranks, in as little as one year in commercial duty even with decent care and good oil.
