You gain more stacks from poisoning champs than from farming - unless you can do both at the same time as you said. However, in solo it is much easier for your opponent to dodge your poison or stay out of range (unless you fight someone like Kata, Kassa, Lissindra, or any of the Assassins).

On bot lane you can not only fully concentrate on poisoning without having to neglect your farm, you even have two champs from which one has to farm making him/her an easy target or your zoning a good option to deny farm.
