What’s the purpose of 3D printing in ABS vs other more modern filaments?

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.

Do you just wipe it down when it's done printing, or is that part of the printing process in a higher end printer?

If you're asking about smoothing you need to build a fume chamber. You want the print bathed in a low steady steam bath of acetone (for ABS) or IPA (for PVB). A sufficient fume chamber isn't difficult to build, you can find instruction all over. But, again, vaporized acetone is hazardous.

Depending on the amount of detail you need to keep, you really can just paint a little acetone straight into the print. You wouldn't want to do that on, say, the face of a figurine, but for flat uniform surfaces is great, and much faster.

I would suggest you can get all the same benefits as abs out of ASA with the advantage it has less shrinkage and warping
