I absolutely agree with 3allawi & Mavii
Fos7a is a good as a first step ,and you should start from it (to see how does the arabic grammar looks like etc ) ,after that you should choose the most understandable accent(my preferences are Syrian+Egyptian) and you should mainly focus on them to be able to understand ppl and communicate with them easily wherever you go
My myself do both at this moment (Fos7a+dialect![]()
