There's no chance that buring is better than a landfill. There's so much empty (useless) surface area on earth. Burning puts poison into the air and requires a ton of energy.
At least here we do have high requirements for burning stuff so you do have proper filters etc.
At the end of the day you probably have concentrated toxins after the burning but handling this shit is probably easier and cheaper than undoing a landfill in 30 years.
