I'm experimenting with the new Logic. It's an incredible upgrade. The Score, however, is still very basic.
As for the lack of symbols, there is nothing one can do for the articulation representation. However, I've started using a trick to add the missing symbols: create a Symbols text style, and use it to add music symbols from the Mac Emoj and Symbols palette. It is not all that different than what you do with a dedicated notation program.
