If you don't wnat the smell - then use pla or pet. Problem solved.
It's not always as simple as that, because choosing a different material means trading a lot more than just one property. If you need something to not melt in a car, PLA won't do the job. ABS also has a lot higher impact resistance. Maybe PET will do though. An enclosure can help with the smell and warp problems.

Also, some ABS is a lot worse than others for smell. So different blends of even the same general type of material can change what you get.
