In no particular order, what I know about champions in these lane:
mid pretty good, but it is best if you end up fighting a mage or AP assassin, as she can use her spell shield to nullify enemy damage
mid is pretty good too, you'll intiate a lot of trades by q'ing in and following up with a w, then walking out with your passive shield to partially ignore the return trade damage
and
top would probably require more tanky builds, which would still be fine with
's AP stacking mechanic, and
's exceptional base AP and AP scallings
AP
mid is pretty brutal with the poke it offers, plus you still get the benefit of the shield and the cc from the rest of the kit, would recommend more of an AP bruiser build though
mid (and
mid for similar reasons) works really well since
can be the normal lane bully he is and force out the enemy laner with his natural tankyness (may want to add extra magic resist to your runes if against mages) and the fact that he is manaless
mid might work, no clue, I haven't seen him outside of the jungle for a couple patches.
