ABS is one of the most heat resistant plastics you can use in a hobby grade printer. A lot of the people I know who use it do so for automotive stuff. Though I see them going more and more with PC these days.
Another benefit to ABS is acetone smoothing. It produces a smooth shiny surface on the print but chemically melting it just a little. It’s all on the toxic side of hobby endeavors. Neither ABS or Acetone produce health friendly fumes. You can also do a similar smoothing affect with PVB filament and IPA.

PLA is biodegradable over several hundred years. The main reason to avoid using it outside is because bright sunlight makes it brittle. That will happen in just a few.
Also abs gives off poisonous styrine vapours you must vent the fumes outside.
