Do you use a magnetic drain plug?

I do. I have used Gold Plug with success in engines, transmissions, and differentials. They collect that fine "paste" of iron, so they're doing something.
My 4 Volvos with automatics came from the factory with magnetic drain plugs. They collect the paste as well. So, I reckon they're working and since it costs extra money to make a magnetic plug, the manufacturer must have figured there was a benefit to that cost.
For some transmissions, there are magnets on the inside of the pan that collect the same paste (e.g. the NAG-1 in both Mercedes) and in that case, I would stick with the factory set up.
I have added magnetic drain plugs to Volvo differentials, and I am really pleased with both the ease of changing fluid, and collection of whatever magnetic debris was in there.

I've since improved the process, using a Time-Sert thread insert in the transfer case (angle gear) for better thread durability.

In what situation is it one or the other?
What's interesting is that in the engine, several engines in my case, even with excellent filters, the plug still collects that fine magnetic paste. Not much of it, but it clearly wasn't caught by the filter.
So, does collecting it make a difference? No actual idea. But pretty sure it doesn't hurt, either.
FWIW I use one of these in my OPE without an oil filter (generator, power washer etc.). If it has a filter I don't use one. I have never used one in a vehicle and probably never will...
Just my $0.02

Yes, I use a Gold magnetic drain plug, in both my Jeeps.
Filter mag makes strong ones
I make my own. Samarium cobalt. I need to make one for my ram.
Got a magnetic drain plug in my old Volvo going on 20 years. Always collects a fine gray paste. Have some strong external magnets on some of the trans pans on my other vehicles.
"Not for the engine". That's why there are oil filters in place.Meaning I would not add a magnet on the engine at all... I thought I made it clear to understand. Maybe more coffee would help.
Yup - typically gold plugs.
Wherever I can get a magnet I use them.
A filter mag will be more effective because of the flows proximity to magnetic flux.
The plug helps clean a bit but is more useful as a diagnostic tool.
I have a 2013 Toyota Tacoma four-wheel drive with the 4 L V6 engine automatic I use the Dimple brand magnetic drain plugs in the front differential transfer case and rear differential when I take the engine drain plug out no visible means of magnetization on it to a very very slight dust that you can barely see on a white napkin also using the regular standard Toyota oil filter for that engine and Alternate the Fram xg3600 version results of the same either way the last time I changed the transfer case and the rear differential I would say that there was very little magnetization magnetized particles I think that is also partly due to using the mobile one 75-90 LS lubrication again I use a Dimple brand magnetic drain plugs because they're supposed to have something nidium type magnet but a search can find them easily they're not cheap but they work very well for my case
In my 2006 Honda Volvo XC90 all-wheel drive I use a magnetic drain plug that I bought from IPC believe they're in Washington state or Oregon and then there's another Volvo aftermarket seller of original parts in Milford Connecticut I can't remember the the name right now same results

Not sure I agree. Ive put a magnet on the filter on my 98 S-10 ZR2, and the (factory supplied) magnetic drain plug still collects a fine paste.

Same here. Good plug is a great option. Dimple also is a great option but $$$.
I run $11 eBay magnetic plugs in my Mercedes’ diesels, because someone modifies oe drain plugs so they fit the (M14?) hole but keep the 13mm head.
Everything I can get a magnetic plug into, gets one…
Have them on all of the fun fleet, mostly for diagnostic purposes; seeing what ferrous material they catch.
Had a long chat w/ our A&P a while back when we first bought our airplane. It came with a strap of magnets around the filter that I was inclined to toss. He recommended we keep it solely as another diagnostic aid in addition to always cutting the filter; if something is being held to the side of the can, you know its ferrous. For that purpose, it works.

Dimpleplug, GoldPlug, PSR, Votex, and even the generic magnetic drainplugs from the local autopart store, all work effectively.
Filtermags work great.
I do not recommended magnets on the outside of a pan.
