I used to swear by impact guns for pulling stuck injectors until I switched to a slide hammer setup last year

For like 5 years I'd just crank the torque up on my 1/2 inch impact and hope for the best on stuck injectors in old Cummins 5.9s. Then I wrecked a cylinder head on a 2001 Dodge in Baton Rouge because the injector sleeve came out with it (huge mistake). Now I use a Proto slide hammer with a threaded adapter and some Kroil oil let it soak overnight first. Has anyone else had better luck with slide hammers over impacts for this kind of job?

Yeah I wrecked a cylinder head on a 2001 Dodge" - that one stung just reading it. Probably cost you a good weekend and some cash. I started using a Mac Tools slide hammer with a blind hole puller attachment on Duramax injectors after watching a buddy strip out three threads with an impact. The slide hammer lets you feel the angle and pressure way better. Still use Kroil soak for 12 hours first though. Heat gun on the injector body helps break the carbon seal too.
