Hey,just to let you know that they is no picture as I can’t answer it.

Overall vertical is visually better, if done correctly
it forces you to "line up" all the common exponents.

most problems are presented horizontally, that becomes the issue to locate the common exponents.
in both cases the biggest issue is people forget
that when subtracting "subtracting a negative is like adding a positive"
-5x - (-8x) = 3x [that is a positive 3x]
or:
-7x
- - 10x
-------------
3x
everyone misses those eventually so you have to watch out for that in both methods
