I get that there are tradeoffs and that logographic languages have advantages and disadvantages.
In this case specifically though there seems to be a pretty strong consensus that one of the advantages of a phonetic alphabet is ease and time to learn.
In a completely phonetic language (which English is obviously not) once a kid learns the alphabet and around 50 phonemes you can represent with it, their auditory and reading vocabulary is roughly the same. So you can have 6 year olds with a reading vocabulary of 20k words.
It’s not that simple, but clearly the more phonetic a language is the easier it is to learn for someone who can already understand the spoken words.
