In general (each guitar of course will vary) a mahogany topped guitar will focus a little more on the lower midrange and midrange, and sound a little warmer/darker/woodier. The A10 has a mahogany top.
A guitar with a spruce top might sound a little more open, and brighter. Spruce is a lighter material, so the top seems to respond a little 'faster' to the vibrations coming to the bridge. Imagine a condenser mic with a very light, thin diaphragm material vs a dynamic mic with a denser or heavier material, and you have an idea of the way the different tops will respond to high frequency content, etc.
Just as with different mics suiting different purposes, each has its sonic territory, and each is equally cool in the right hands.
But so much depends on the individual instrument.
Both are capable of sounding great, pick your poison.
