My views are an opinion, and i am just stating my own personal preference. I am sure that you will find a number of people in the field that would agree with you.
I just wouldnt call it advanced. its okay for a for lets say a B737 travelling MAN-IBZ with 150 holiday makers and a few bags, because not a great deal of planning or thought is needed, but in my experience it is not AS geared up for say a A340-600 going from LHR-SFO., where a vast number of factors/options are required and will change. Again, this may simply just be customer specific, as i can only comment on my own use. Certain options are just not available, and use compared to babs/codeco etc simply involves a lot of huffing and puffing compared to a few simple keystrokes!
Again, i'm not saying anybody is wrong, but i can only say that from personal preference, i hate it!
