Subject and verb agreement expressed in two ways

Based on an earlier question which was deemed a duplicate, I'm submitting a differently worded question which I'm certain has not been asked before.

The following two sentences, in my opinion, say pretty much the same thing. (If you think they do not, feel free to let me know, and why.) One sentence is as I found it, and the other sentence is my rewording of the original sentence. I won't tell you which sentence is which.

• “What you see and what you hear depends a great deal on where you are standing. It also depends on what sort of person you are.”

• "What you see and what you hear depend a great deal on where you are standing. They also depend on what sort of person you are."

Is the way in which one sentence is worded preferable grammatically or stylistically to the way in which the other sentence is worded, or do we have a case of "six of one, half dozen of the other"?

They're both grammatical and in acceptable style, they just have slightly different nuances.

If you use the singular verb, you're treating "what you see and what you hear" as a single, combined concept, your entire sensory experience.

If you use the plural verb, you're considering them independently, like saying

What you see depends on where you're standing, and what you hear also depends on where you're standing.
