I use the Staff View (notation) about 90% of the time. It does need improvement, but it works fine for me for writing and arranging.
My biggest complaint is that it does not know how to notate swing time (that is, 4/4 with triplet 8ths—or 12/8 counted in 4/4, depending on how you look at it). It notates triplets, but only if they are all in the same staff and it has no idea how to notate a quarter followed by an eighth in triple/swing time.
