Best option of all is not to buy plastic in the first place. We didn't need it 50 years ago, so there is no need for it now, except convenience and laziness.
But since we got all that shitt, then I think it is still better to recycle. There are different recycling routes, and some lead to the materials being fed back into "the system". If it goes into landfill it just sits there, for centuries apparently.
If everything went into landfill, the practice would disappear from public awareness and the consumption of raw materials would just escalate. At least if there are ugly piles building up somewhere for people to video, people become aware of what is happening and some are compelled to do something about it.
