I would say it all depends what you want.
If you like layovers and LH flying....wait for the A300
If you would rather be home a little bit more and you like to be typerated on a modern machine, internationally demanded....take the 320
But since you are saying you have none of the types....I would say go for the A320 type rating! Its worth a lot more on the market whilst a A300 type is worth bullocks!
A320 type is gold mate!!!Just check the number of joboffers around! And after all, you never know whats going to happen with you personally here....No offence but thats the truth. Its a hard world outhere, you have to protect yourself...
Up to you Habibi.
