I would just note that the automotive repair industry seems to prefer pneumatic sanders. I suspect that part of the reason is that they already have large capacity compressors, but also for prolonged sanding sessions, the pneumatic sanders do not get hot. The long pneumatic hose would be an issue.
Most smaller compressors have the PSI requirements down pat, but the CFM requirements frequently exceed the capacity of the smaller compressors.
In any case, compressed air sanders should be in the mix when considering sanders.
Small, light and cheap, but no dust collection shown. The Eastwood pneumatic is $58.00.
This is absolutely true. When I started in the cabinet shop, I was quite surprised to see the difference. During my time, in the body shop, we used 6" PSA pneumatic sanders. The cabinet shop was using 5" hook & loop, also pneumatic. Neither did anything about dust extraction, at that time. Many years later, as I got into Festool, an RO 90 became my first electric sander. I used it for the Rotex functionality.
All along, the rest of the shop stayed with 5", everybody had one. To this day, none of them use extraction.
The 5" standard was the reason I got an ETS EC as my next electric. It was easier to get the boss to buy sanding discs with the Festool pattern, rather than the regular no-hole stuff.
That is also the reason I have a 125 for the bigger RO too.
Of all silly things though, when they bought an extractor and an RO, for Corian installation/repairs in the field.....the got a 150?
I had a pneumatic, like everybody else,(still do) but I don't use it much anymore. I do have the compressor capacity at home, but I try even harder to keep the dust down, in the tiny shop.
What I never got was the juxtaposition? The body shop was sanding curves and the cabinet shop, mostly flat. Wouldn't the smaller 5", with the softer H&L paper be better? And wouldn't the larger 6" with a harder PSA pad, be better for flat work? But they all do it, not an anomaly.
Granted, there is another difference though. The automotive sanders are the traditional pistol grip D/A type, which are lockable, similar to Rotex. The Cabinet shops use the smaller palm style, with the top flap switch.
I have never adopted the 6", going straight to the 8" PSA geared orbital, for Corian fabrication.
PSA is a giant pain, if you change paper frequently. Yet another reason, beyond dust, to limit its use.
