Flat AD help you last hit Flat Arpen doesnt as minions start at 0 AR .With nothing happens till 15mins current meta ofc AD is better.

But you will deal more damage to players with ARpen Marks+AD Quints setup (15 ARpen/6.75 AD) as nowaday ppl usually get AR seals.

Then it depend on how aggressive you are not which champ are you playing.

Well there are some champs you will want to play more aggressive thou. EX : Tristana,EZ,Graves.

Tristana is an exception as her early damage is magicial and her based AD is super low, full AD for Tris.

ARpen runes synergy very well with Black clever. Thus if you know you will get a BC even before the game start and you aint being aggressive get ARpen Quints and AD marks.(8.5AD/10ARpen).
