PLA is easy, compared to ASA. Virtually no warping with PLA, but you cannot use a vapor bath to remove print lines and strengthen the part. Sanding is about your only recourse.

I detest supports as well. ASA supports are a pain in the butt. It drove me to acquire the MMU (multi-media unit) for my MK4S so I could print supports with PLA. Makes it much easier and cleaner to remove them. Fortunately the MK4S can print up to a 75 degree angle before it needs supports.
