Mozart Sonata K.310 - 2nd movement grace notes

[perprocrastinate]

In the comparison of these three editions:

On the first page of the second movement, in measure 10 (all editions), the fingering differs for the sequence of grace notes. The first edition uses finger 4, which I assume is for a legato touch, while the second edition uses only fingers 2 and 3, which I assume is for a detached touch. There are no articulation marks, so I can only guess at this point. The third edition slurs groups of two, implying the fingering of the second edition.

Now, I know interpretation is a personal matter, but which version is more accepted, or which version fits better in context of the movement?

1 & 3 have the grace notes as appoggiaturas (3 writes them out into the score), and 2 has them as acciaccaturas.  That seems to me to be the big difference between them.

1 & 3 are actually identical at this point, though look the most different.

FWIW, I actually do something about halfway between here.
 
Whether you use 4-3 or 3-2 seems to make little difference, so go for the more natural feel.
