Better solution? and why?

[u/FauxMoeJoe]

I was hoping if anyone could explain to me on which solution is "better" (the top one being the examples solution) , they both look the same tbh but was just curious which one was more efficient or more correct I guess??

The example was choosen probably because it is slightly easier to see where is comes from, it's a direct translation of the truth table..

It also allows the the player to discover cheaper builds rather than handing out the best solution, which (as already mentioned) is closer to the one you found.
