The only thing I can add to this - (I have a PC and a Makita) is if you are using a rotary, you have to be careful with painted trim pieces like door moldings and bumpers. A rotary can (been there-done that) roll the paint off plastic. It was entirely my fault, I was trying to get too close to a piece of trim and was too stupid - should have taped it up. But, I learned from that and moved on. If you have a detail where the paint is in bad shape, you can do Megs 105 on wool, followed by Ultrafina on 3M blue foam and get fantastic results in much less time than you would spend with a PC, especially on black paint.
Most details I get lately can be polished up with just Ultrafina or
Menzerna FFII, use a soft foam pad like 3M or LC gray-or white and you're done. Just tape up trim!
