Well, I personally don’t have any experience using either for forged pieces, but what immediately comes to mind that you might think about is that with a sandblaster, you would be manually removing scale and whatnot piece by piece, whereas in a tumbler, you would toss in several pieces at once and turn the machine on while you do something else.

Just having some fun messing around with whatever I have a mind to do.

Sand Blaster is the only option for large or weird shaped pieces.
Sand Blaster needs protection face/suit, and area cause it makes a sandune in your area if you use it alot, plus you have to buy sand/media.
Tumblers bigger than 2 feet make noise like a Roadgrader or a Jet Airplane and will bring all neighbors to your door. tumbles or Media depends on effect. From walnut shells to pieces of ceramic or steel, (most use junk/cutoff bits of steel) Will quickly wear out detail in things like animal heads.
Have worked with a thick shell 8ft by 2 ft with a chain-drive motor, just the lid was so heavy it needed a cable hoist. Noise was crazy. You need a vacuum attached to the end to remove the wastage/Sand/scale.
Also 4 foot by 3ft thin shell very noisy with metal tumbles, small ones use other media sometimes with ceramic but you get a different effect and more wastage.
All are kind of messy; but tumbler gives best look. timing is important as you just want to knock off the scale not wear away the pieces. Also you almost lose any small pieces under 6 inches just looking in the media when it is finished tumbling.
If all small pieces under 2 ft you can use a small tumbler or a sandcabinet Blaster, closer call there but same issues.
