Learning with Arabic letters is definitely better because all the logic, grammar and construction of the language is tied with the letters and recognizing the pattern is only possible if you learn it with Arabic script. I started with Roman script, but all the grammar rules never made sense to me until I started learning with Arabic script. I think it's a lot better.

Arabic alphabet is the origin. I think learning by the Arabic alphbet is better.
