NOTATIO

Larger noteheads bring the notes to the foreground and I have always found them to be much easier to read.

I find the upper one preferable as it concentrates the relevant information. Dogmatically moving the text further away from the staff to avoid a collision makes it harder to understand all three directions at a glance.

Ledger lines should, at a minimum, be thicker enough than staff lines so that they subjectively appear the same thickness as staff lines. I go further than that, because I believe it's easier to count just ledger lines at a distance than staff lines + ledger lines. In the Schenker edition of Beethov...

I agree that MuseScore has basically surpassed Finale's default output. My comment was more that Baerenreiter would probably balk at using an open-source program and go with something commercial.

The slurs are the giveaway. The note spacing is too good (not saying much) to be Sibelius, I can't imagine them using MuseScore, and it's definitely not LilyPond.

Software looks to be Finale with Palatino Linotype and the Vienna music font.

John, is the slur in m.3 RH an error in the first edition or in the Baerenreiter?

Not only are the noteheads too small, the staff size is smaller than the Schenker edition and most piano scores I've seen, including past Baerenreiter keyboard scores.

How fast is usual? To me, it always depends on the character and mood of the piece, and there is no default speed. For anything out of character with the piece, it might be best to write it out as in Beethoven Op. 31/2 mvt. 3.

The 8va text looks to just be boilerplate italic New Century Schoolbook.

MuseScore's default is definitely the best, but I think I still prefer John's overall for consistency with engraved scores.
