The NGK plugs are like $8ea when you buy 16. Still costs you nearly $800 less than what the dealer cost for that job is. And they last 60-75k miles.
Pros: last 60-75k miles
Cons: pain in the ass

Spark plugs do actually vary for some reason, I always use whats oem to the car. In my case thats the ngk iridium plugs (same goes for cables).
Vehicle:
Subaru Impreza
Fitting a decent set (Denso or NGK) of iridium plugs is also worthwhile.
Pros: worthwhile
Vehicle:
Subaru Legacy
Believe it or not I got the Genuine AC Delco iridiums from Home Depot for $3 a plug.
Pros: cheap, genuine
I changed the spark plugs in my nieces 2.5L VW Jetta because it was idling at 1300rpm. Rock solid idle at 700rpm afterwards. Easy way to save some gas.
Pros: rock solid idle
Vehicle:
Volkswagen Jetta

Vehicle:

I recently took my stage 2 43K mile b8.5 s4 apart and did the PCV, water pump, thermostat, new 2 step colder brisk spark plugs gapped to .25. I took the spark plugs out and noticed heavy carbon and the ground electrode was white, even on all plugs . (20 miles on plugs)
Cons: heavy carbon, white electrode
Vehicle:
Audi S4
Mileage: 69202 km
I now dread doing spark plugs. Something that’s super easy to do on most 4 cyl cars is a PITA doing on my ej25.
Cons: spark plugs difficult to replace
