With around 60% crit with 3 items, it's no thing of luck anymore and if you smiply compare numbers, you will see that crit item builds in general outclass the lethality items at the 2/3 item mark. The old armor pen indeed was better on champs that could use this stat, but lethality is not. It's inefficient and not worth it's cost.

The big advantage of the old armor pen items was that they were very efficient alone, with one item alone you were good to go and had a big powerspike. later in the game you were able to deal true damage to the emey adc, what doesn't mean THAT much because adc's don't get that much armor, but still it was good. In late game in naturally was worse than the crit build, because the damage numbers were general lower and as I said, the armor of adc's isn't that high. Now lethality isn't as good early on as armor pen was, because it has a level scaling, making the one item power spike a lot weaker and by the second item crit allready starts to be stronger.

And don't come with "but armor pen is better against tanks", no. Flat armor pen or in this case lethality doesn't make any difference for a tanky. Whether he reduces your damage with his full 200 armor or with 160 after your pen is calculated, it doesn't make a difference. Only Black Cleaver is somewhat good against tanks, but it needs time to stack, which isn't easy in general and for Miss Fortune only with her (especially for tanks) easy interruptable ult. Then there is Last Whisper, but both Item Builds have this item, so it's not worth mentioning in this discussion. Although the crit item build has an edge here too, because this item build will have a lot more atack speed build in and thus more possibilities to use Last Whisper for burning down tanks.

TL;DR Armor Pen builds were strong, because they were efficient early in the game and with only one item, so crit ADC's couldn't catch up and got rekt before they could build their items, but with lethality now being level dependant this is no longer given.
