A solo lane, is a solo lane, is a solo lane.
The only difference is the Nuances of the lane. Top lane is longer, thus more dangerous when over extending, and it's remoteness means you would probably rely on TP for map pressure. While Mid lane is shorter, thus harder to get ganked. And being in the center of the map offers more opportunities to apply pressure.
Other than that, You CS the same, and you get solo XP the same. You could say that certain champs synergize with a particular position, due to those nuances. But you can have a GP mid or a Liss Top, and they will still perform the same way.
